Has anyone used claws-mail with proton email, via protonbridge, or otherwise? claws-mail requires a fairly manual setup, and protonbridge is pretty sparse with the information it provides.

I'm working on a monitoring application for my home gateway and I want to know the device type of all connected clients. For that purpose I'm using tcpdump to extract the user-agent of all devices tcpdump -vvAls0 | grep 'User-Agent:' but I can't figure out each client user-agent. is there a way to distinct the correspondent user-agent for each device.

I'm trying to use k-9 mail on android to connect to my organization's IMAP server which is being run as an **outlook.office365.com** service. As I'm sure many of you know, Microsoft recently turned off *Basic Authentication* which is how I previously connected. While this no longer works, I should be able to use OAuth2 which is supported by both server and client. However, when connecting and then authenticating I then get the following error. I should note, I am able to use the OAuth2 authentication in Thunderbird on Linux. Since, IMAP is the actual protocol being used in both cases, I'm guessing that the only difference is the "User Agent" string being sent to the server in the android case. **How do I configure K-9 to use the same user agent string as I see sent from my Linux machine?**

I run claws-mail on multiple computers and would like to synchronise the configuration and address books. Is there some canonical way to do this? I couldn’t find instructions in the manual and I don't want to sync the whole ~/.claws-mail folder if possible.

I can send email from my gmail account by ssmtp in Linux now. But how can I attach files to the email?

How to setup the email client Mutt to send, receive and read email under CentOS and Ubuntu using a Gmail account as a relay

I wanted to use Geary as my mail client instead of Thunderbird. But I don't know if it supports Right-to-Left text! (I want to be able to write languages like Persian, Arabic, Hebrew etc)

I'm receiving "You have mail" messages and according to How to remove “You have mail” welcome message I should read my mail with mail. However I cannot find the command in my system (Ubuntu 10.04 server). What do I need to install?

I've got problems setting up the notifications for Evolution. I already installed mail-indicator-evolution and evolution-indicator but neither of them appear in the notification area. How can I properly set it up? Besides, I'd like the mail to be updated automatically without a window open. I'm using the MATE desktop environment.

I use a laptop without a mouse as my main work system, and I could really use a fully keyboard-driven email client with graphics support. Right now I have the option of using GUI clients, which, even if they support the keyboard, are optimized for the mouse (buttons and menus taking screen space, actions based on navigating menus with the arrow keys, etc) or terminal-based clients, which don't support embedded images in HTML messages. Is there something that tries to mix the best of both worlds?

Is there any command in unix to check a pop3 account using terminal? I mean, type the server/username/password of a pop3 account and see if the username/password is correct?

I have in the past heard of using nail for this task, but I can't seem to find it for my distribution (Ubuntu 11.04) in any of the repositories. What program can I use to one-off emails from a shell like so: send-mail -to me@email.com -file attachment.zip -message "Hello World" Is there a program out there through which I can script mail sending as above?

In Balsa 2.5.1 is it possible to connect to SMTP with port 465 with SSL? The IMAP setup has an SSL option which disables the TLS choices, but I do not see anything similar when setting up SMTP. I know that SMTP port 587 with STARTTLS is the standard-compliant way to connect (and the same with IMAP port 143 STARTTLS vs IMAP port 993 SSL), but my mail service doesn't seem to support this yet. I have tried every combination I can come up with in the SMTP settings in Balsa, but nothing seems to work. I have been able to connect in every other email client I have used, so I don't think there is any problem with the server (other than supporting the latest standards, ha). Also, when using the compose window in Balsa and typing in the To field, after hitting tab it takes you to another To field and you have to hit tab once or twice more to get to the Subject field. Is there any way to have the tab press after typing the first To address take you directly to the Subject field (I didn't notice anything in the options, but perhaps I overlooked it)? Thank you.

I'm using Mutt as my main email client, but I'm looking for another one for my work email (because of HTML email). I need one that can handle my existing Maildir email, to be able to switch between Mutt and the new one without having to import/export my old emails. Does anyone know such email client?. Also I don't want to stop using Fetchmail, Procmail and Exim4. It would be nice to find something similar to Mutt, but with better HTML answering abilities.

Why doesn't the list command work in mail? When I try l or list, it doesn't work. It instead gives me a list of the valid commands, including list. Commands are: next, alias, print, type, Type, Print, visual, top, touch, preserve, delete, dp, dt, undelete, unset, mail, mbox, more, page, More, Page, unread, U, !, copy, chdir, cd, save, source, set, shell, version, group, write, from, file, folder, folders, ?, z, headers, help, =, Reply, Respond, reply, respond, edit, echo, quit, list, xit, exit, size, hold, if, else, endif, alternates, ignore, discard, retain, saveignore, savediscard, saveretain, core, #, clobber **Edit:** # cat /etc/redhat-release CentOS release 5.5 (Final) # mail --version mail: invalid option -- - Usage: mail [-iInv] [-s subject] [-c cc-addr] [-b bcc-addr] to-addr ...

But I'll be happy to know how to do it on just one.

My email is kept on a remote server and accessible from anywhere by IMAP. What I'd like is a mail client that will periodically sync that remote mail to my laptop in the backgroun, so that when I open my mail client, today's email is instantly there and does not need to be downloaded. The background sync process could be some separate daemon or a function of the mail client itself. What I have now is just Thunderbird accessing the remote mail server via IMAP. But it means that mail only syncs when I start Thunderbird, and it takes ages to do so before I can read it. It's a slow process. I have a feeling that fetchmail could form part of what I want, as it can download mail to a local maildir. But then what's the easiest way to access this mail locally? And would fetchmail be smart enough to handle two-way sync, so that when I delete, move or save a mail locally the change will make its way to my remote IMAP server? Or is there some other Thunderbird-like mail client that can sync in the background (I work in Gnome), solving my problem?

I don't like threaded email views as much as the inline "[conversation view](http://mail.google.com/support/bin/answer.py?answer=5900) " of gmail, however gmail is not as fast as I'd like it to be. Are there any desktop clients which provide a "[conversation view](http://mail.google.com/support/bin/answer.py?answer=5900) "?
