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'm sending email from a script using mailx. The script is run daily by systemd, using .service and .timer files. For testing purposes I'm sending from the command line. The mail is sent with the command echo "Test message - you know the drill" | mailx -r "localweb@example.uk" -s "Test Message" a.user@example.com (personal data replaced for privacy) This works. It's relayed by postfix to my gateway server (also postfix) which signs the outgoing message. This is then delivered to GMail which verifies the SPF data and DKIM signature, and the message is delivered to my inbox. This is good, except it's displayed as Ubuntu I have other servers sending mail by the same method, and they all display similarly. I'd like to change the display name to something more useful, per server. For example, Web Server but something I'm doing is messing up the From address as it travels to the gateway server. I've tried echo "Test message - you know the drill" | mailx -r "Web Server localweb@example.uk" -s "Test Message" a.user@example.com and echo "Test message - you know the drill" | mailx -r "Web Server " -s "Test Message" a.user@example.com But in both cases the From address is somehow lost by the local PostFix, and the message sent to the gateway server has a from address of localweb@smtp.private.example.uk where smtp.private.example.uk is the FQDN of the gateway server. This is sent to GMail, but fails the SPF and DKIM tests and is unceremoniously dumped in spam as a result. (I don't know how the local postfix is getting the name of the gateway server) So, how can I add the display name to the parameters I pass to mailx such that it survives the journey from server to server and is displayed correctly by GMail? Mailx version 3.14 (GNU Mailutils) Ubuntu 22.04 I've made only one change to main.cf for PostFix: added a relay-host address for the gateway server.

I am generating output file (.xls format) from the below DB query- sqlplus -S -L user/pass@DB > home/test/query_output.xls set line 22000 set head off set feedback off SELECT * from table; EOF The query_output.xls file contains records as below- VIM 00 34562356 22412299 Dated 11-JUN-18 OMM sansra carla Yes No No No 02356478 14-SEP-18 To send this query_output.xls file as an attachment in email, I am using below- uuencode home/test/ query_output.xls | mailx -s "Subject" me@Domain.com Also tried uuencode query_output.xls query_output.xls | mailx -s "Subject" me@Domain.com But not getting the data in attachment received in email. Also tried mailx -a and mutt but its showing 'illegal option -- a' and 'command not found' resp. mailx -a home/test/query_output.xls -s "Subject" me@Domain.com < /dev/null mutt -a query_output.xls query_output.xls < /dev/null also tried mailx -s "Subject" me@Domain.com < query_output.xls but no attachment received. Could you please help?

As described in the subject, mailx -a somefile.txt -s "blah blah" myaddress@bigcorp.com hangs, while emails sent via cat somefile.txt | mailx -s "blah blah" myaddress@bigcorp.com arrive. The /etc/postfix/main.cf relayhost variable is set to our corporate mail server. In a certainly related note, mail sent via mutt (with smtp_url pointing to the same corporate mail server as the postfix relayhost) seemingly disappears into the bit bucket. echo "" | mutt -s "this is a test" myaddress@bigcorp.com This all was working perfectly until late last month. None of the files in /etc/postfix have changed in 2+ years, so I wonder if the mail server was reconfigured.

I've to send a HTML file with mailx command but when I receive the email with the mark up code showed like this : Title One /TITLE> body { width:900px; font-size: 10pt; font-family:verdana; .../... I used this command : cat file.html | mailx -r dude1@acme.com -s "Suject" -S content_type=text/html -S smtp=smtp.acme.com dude2@acme.com I tried this one too cat file.html | mailx -a 'Content-Type: text/html' -r dude1@acme.com -s "Suject" -S content_type=text/html -S smtp=smtp.acme.com dude2@acme.com I got this error message with this last one above : Content-Type: text/html: No such file or directory What is missing in the -a option ?

I'm writing a bash script that sends an e-mail with attachment to the local user root. I noticed that mailx forks some helper program and terminates instantly with exit status 0 even when the command line arguments are invalid:

localhost:~/basinsrv # mailx -s aaa root -a bbb 

How to make mailx wait for the outcome and terminate with proper error code? Actually, I need to post-process the generated mail before it's sent. Is it possible to not actually send the message and only save it to a file? mailx-12.5-31.7.x86_64 postfix-3.6.2-7.1.x86_64
