I have OpenWRT router, installed msmtp. I would like to write a command line (or a .sh file) that would send me the current public IP address, and let cron execute it every 15 Min. I found the posting: https://unix.stackexchange.com/questions/537082/run-a-command-and-email-the-output and tried to do the same with msmtp, and it did work: I did the following kdig +short myip.opendns.com @resolver1.opendns.com | msmtp xxxxxxxx@gmail.com and got an email with the current public IP address, but without a subject, of course, because I didn't set anything. Now, for msmtp, the way to put a subject is echo "Subject: Current Public IP" | msmtp xxxxxxx@gmail.com But I have no idea how I could combine these two things.... I would appreciate your help very much !

I am trying to write a script to send an email whenever a usb device is connected to my computer (Arch Linux). The code I wrote is

#!/bin/bash
if [[ ! -z "$1" ]]; then
	echo "USB inserted at $(date) for $1 and $2" >> /home/user/commands/logs.log
	cd ~
	ip -4 addr | grep -oP '(? /home/user/commands/testing.txt
	echo -e "Subject: Hello \n\nBody:usb inserted at $(ip -4 addr | grep -oP '(?<=inet\s)\d+(\.\d+){3}')\nthrough the mail" | msmtp mymail@gmail.com
fi

the script is supposed to send the ipv4 address to the mail. The usb insertion is being detected and the log file and testing txt file is being written. But the mail is not being sent. I wrote the mail code separately through the terminal and it seems to be working. But inside the code, the mail is not getting run. I have set the msmtp working. I have checked using terminal commands directly and it is working. But through the script it is not working. All other commands are getting executed and I am getting the files. This is my rules script

ACTION=="add",\
SUBSYSTEMS=="usb",\
ENV{DEVTYPE}=="usb_device",\
RUN+="/usr/local/bin/usbinserted.sh '%E{DEVTYPE}' '%E{DEVNAME}'"

I have the following things not working in my neomutt application: 1. Email is displayed instead of Username. For example : johndoe@example.com is displayed instead of John Doe . 2. How to ensure that Neomutt applies the Standard TLS encryption for security similar to Gmail, which encrypts emails on transit? Neomutt MSMTP config

msmtp: could not send mail (account default from /home/admin/.msmtprc)

I've come across different names in different places: Light MTA, Remote MTA, Smarthost, etc. Generally, I do not want to install a full-fledged mail server (such as sendmail, postfix, exim), but only send notifications/emails using an existing external ISP/mail provider (such as dismail.de, mailfence.com or others) with unattended-upgrades, cron, smartmontools, my own bash scripts etc from all over the system. Additionally, it would be ideal if there was support for queuing and retrying (an attempt to resend in the event of being offline or temporarily unreachable by the mail provider) So far I've found: - ssmtp - msmtp - s-nail - nullmailer - dma - esmtp But I didn't find any comparison between them. 1. Does anyone know what makes the program stand out from the rest? (positives, negatives, ease of configuration, low resource consumption, etc.) 2. Possibly I missed something and maybe there is another one, better than all those mentioned for Debian? 3. Did I understand correctly that s-nail is also an MUA and bsd-mailx or mailutils is not needed? Maybe others too?

I have configured my Debian server to use msmtp for sending mails. Current use case are for example sending a daily report from logwatch to my isp email. echo "$body" | mutt -s "$topic" -- "myisp@email.com" I have configured msmtp by means of a global msmtprc file located at /etc/msmtprc. Contents shown below. The next thing I want to configure is that my email for my root account (e.g., output from crontabs) is sent to my isp email as well. I have googled around and found, for example on the Arch wiki, that I should just configure my aliases. Which I have done so at the bottom of the msmtp configuration file. However, after running newaliases, and trying to execute echo test | mail -s "test message" root I get the error send-mail: /etc/aliases: line 2: invalid address 'postmaster' Can't send mail: sendmail process failed with error code 78 I am unsure how I can fix this. The alias shown below is what was already present. I only added the gmail address. I think I could just put a new aliases file but that might break other services that rely on this. I.e., I don't know what the proper way to fix this is. # /etc/aliases # /etc/aliases mailer-daemon: postmaster postmaster: root nobody: root hostmaster: root usenet: root news: root webmaster: root www: root ftp: root abuse: root noc: root security: root root: christphe, christophe.detroyer@gmail.com # /etc/msmtprc # ------------------------------------------------------------------------------ # msmtp System Wide Configuration file # ------------------------------------------------------------------------------ # A system wide configuration is optional. # If it exists, it usually defines a default account. # This allows msmtp to be used like /usr/sbin/sendmail. # ------------------------------------------------------------------------------ # Accounts # ------------------------------------------------------------------------------ account isp host mail.isp.net port 587 from admin@isp.com auth login user admin@isp.com password foobar syslog LOG_MAIL logfile /var/log/msmtp.log # ------------------------------------------------------------------------------ # Configurations # ------------------------------------------------------------------------------ # Construct envelope-from addresses of the form "user@oursite.example". #auto_from on #maildomain fermmy.server # Use TLS. tls on tls_starttls on tls_trust_file /etc/ssl/certs/ca-certificates.crt # Syslog logging with facility LOG_MAIL instead of the default LOG_USER. # Must be done within "account" sub-section above #syslog LOG_MAIL # Set a default account account default : isp aliases /etc/aliases # ------------------------------------------------------------------------------#

I'm using msmtp to deliver system email from an Ubuntu server via an SMTP account. Can I somehow configure this setup to rewrite **all** emails to one specific **recipient address**? If so, how? Or put differently, I don't want any arbitrary PHP script or otherwise to be able to send email to anybody that is not me. I should be the only person that receives any email generated by any script on the server. All while only using msmtp (not using postfix or some other server).

I am trying to get all my system emails to be forwarded to my gmail address, using msmtp 1.8.3 and /etc/aliases on debian. It works, but I get errors from gmail. When I email root (via echo "hello world" | mail -s "forward me" root), I obtain 2 emails in the inbox of the gmail address: 1. The expected forwarded email 2. The following message from mailer-daemon@googlemail.com

Address not found
Your message wasn't delivered to root@backupbox because the domain backupbox couldn't be found. Check for typos or unnecessary spaces and try again.
The response was:

DNS Error: 5452395 DNS type 'mx' lookup of backupbox responded with code NXDOMAIN Domain name not found: backupbox

Obviously, it is not surprising that gmail cannot reach root@backupbox, since from their perspective, backupbox is not a fully qualified domain name. I am however surprised, because I aliased all my system addresses to my gmail address. Here is my msmtp configuration: # /etc/msmtprc defaults port 587 tls on tls_trust_file /etc/ssl/certs/ca-certificates.crt account gmail host smtp.gmail.com from me@gmail.com auth on user me password xxxxxxxxxxxxxxxx account default : gmail aliases /etc/aliases Here are my system aliases # /etc/aliases default: me+backupbox@gmail.com How do I make sure that only the first email reaches me? For example, can msmtp rewrite root@backupbox as me@gmail.com?

I have installed msmtp , and it seems to be working OK: echo "Hello" | mail -s "Testing SmSMTP" destination@gmail.com The email arrives to destination, But the From field is a **ugly** email text like johnsmithsales@hotmail.com . I mean: johnsmithsales@hotmail.com is **correct**, of course, but I would like the receiver to read some **more professional** John Smith - Sales Department , like it can be done on any other email client. What is the **proper way** to achieve this with MSMTP? **Further notes**: - I am running **Ubuntu** v20.04 . - I have installed the **packages** msmtp msmtp-mta mailutils.

I'm struggling to find a solution. I installed heirloom-mailx and msmtp following this site . I can send emails (using gmail) as root user. The problem is with non-root user: the messages go to a queue folder (/var/spool/mqueue) and never are sent. I have little experience with linux. Could you help me?

msmtp is successfully installed and works fine to send emails via an external SMTP server. However the mail command fails to send emails using *GNU Mailutils* on a Debian 10. for example echo "Test" | mail personal@external.email returns mail: cannot send message: Process exited with a non-zero status and echo $? returns "36" I'm supposing this is a msmtp is not integrating with the mail command. How do I configure mail to send messages through msmtp? EDIT: The programs seem to be communicating because the keyring prompt pops up and the login options are set only in ~/.msmtprc

I recently set up a new Pi 4 (running Buster) and installed msmtp and mailutils. I previously did this on two other Pi4s (also running Buster) on which this has worked perfectly. On the new machine it fails. I must have done something wrong, but I can't figure out what it is: Fails:

pi@raspmountain:~ $ mail me@mac.com
Cc:
Subject: sub
body
cannot send message: Process exited with a non-zero status

Works:

pi@raspsky:~ $ mail me@mac.com
Cc:
Subject: sub
body
pi@raspsky:~ $

Here's the log entry for the one that works:

Mar 11 14:53:30 host=smtp.gmail.com tls=on auth=on user=me 
from=pi@raspsky recipients=me@mac.com mailsize=132 
smtpstatus=250 smtpmsg='250 2.0.0 OK  1615449210 
c193sm1615010pfc.180 - gsmtp' exitcode=EX_OK

The one that fails does not result in any log entries. On the new Pi I used the exact same configuration file as on the older Pi: This is the one that works:

pi@raspsky:~ $ ls -la .msmtprc
-rw------- 1 pi pi 613 May 29  2020 .msmtprc

This is the one that doesn't:

pi@raspmountain:~ $ ls -la .msmtprc
-rwxr--r-- 1 pi pi 613 Feb 22 05:46 .msmtprc

Mail points to the same binary on both machines:

pi@raspmountain:~ $ ls -la /etc/alternatives/mail
lrwxrwxrwx 1 root root 23 Mar 11 13:34 /etc/alternatives/mail -> /usr/bin/mail.mailutils

pi@raspsky:~ $ ls -la /etc/alternatives/mail
lrwxrwxrwx 1 root root 23 Oct 21  2019 /etc/alternatives/mail -> /usr/bin/mail.mailutils

What have I done wrong here?

I have a XEN server with someVMs, one of them is the email server. How do I tell DOM0 to send all root emails to my administration email, which is inside the email-VM? I tried install msmtpd and added the config file /etc/msmtprc:

# A system wide configuration file is optional.
# If it exists, it usually defines a default account.
# This allows msmtp to be used like /usr/sbin/sendmail.
account default

# The SMTP smarthost
host mail.myOtherVM.de

# Use TLS on port 465
port 587
tls on
tls_starttls on

# Construct envelope-from addresses of the form "user@oursite.example"
from %U@oursite.example

# Syslog logging with facility LOG_MAIL instead of the default LOG_USER
syslog LOG_MAIL

But When trying to send an email with echo -e "Subject: msmtp test\nhello test." | msmtp rubo77@mydomain.de on my email VM I get the error:

lost connection after DATA from unknown[2a01:xxxx:1d02::2]

(I also tried port 465 but that one is not open at all.)

I'm very new to Linux (Raspbian at Raspberry Pi 4 Model B) and I just try to send an e-mail via command line.

I configured swatch to send alerts about threats through "mail" command. The problem is that it is sending me many same alerts, for example while I'm testing ping I can get like 8 e-mails etc. Does anyone know how to limit amount of mails being sended about one alert?

I use mutt with two different *imap* accounts, and have configured smtp accounts **A** and **B** with msmtp and mutt. If I don't specify a default account in .msmtprc, mutt complains there is no default account when I try to send. If I set a default account **A**, mutt uses this for all imap accounts. *How can I make it use the smtp account **B** for the corresponding imap account?* In the account **B** mutt config file I've set the following: ## sent set sendmail="/usr/bin/msmtp" set use_from=yes set realname="My Name" set from=my@gmail.com set hostname="gmail.com" set ssl_force_tls=yes set imap_pass=$my_pass unset ssl_starttls in .msmtprc the account configuration reads: defaults tls on port 587 [...] account gmail tls_fingerprint 39:7C:59:20:DE:55:51:F4:8B:72:1D:B5:B2:26:8A:D1:DB:90:C6:28:80:77:F9:B5:EC:C1:BF:1C:6F:4D:A1:63 from my@gmail.com host smtp.gmail.com auth on user my@gmail.com passwordeval gpg2 --no-tty -q -d ~/mygmail.gpg

I am using Ubuntu 15.10 and I have an email account configured on the terminal. Probably a left-over from the time I tried to configure that account, I have some logs being printed to a file in my home directory a couple of times day. An example of a log (one line, split here for readability): 28 12:36:02 host=smtp.gmail.com tls=on auth=on user=***@gmail.com from=***@gmail.com recipients=&&& smtpstatus=553 smtpmsg='553 5.1.2 The recipient address is not a valid RFC-5321 address. q65sm28155223wmd.6 - gsmtp' errormsg='recipient address &&& not accepted by the server' exitcode=EX_DATAERR It is printed to ~/msmtp.log My question is how can I discover where does this printing comes from in order to kill it? Solution: The log was printed by msmtp itself. A quick look at the msmtp manfile showed that the configuration file is ~/.msmtprc . I edited this file to change the log file.
