UW IMAP
Although it has not been actively developed in many years, it still works well as a basic IMAPS server. (For other IMAP servers, see Mail server#POP3/IMAP servers.)
From Wikipedia:
- UW IMAP is the reference server implementation of the IMAP protocol, developed at the University of Washington.
Installation
In arch, UW IMAP is simply called imap.
Setup
Although it was originally designed to be used with inetd, on modern Arch systems a better solution is to use a systemd socket file:
/etc/systemd/system/imaps.socket
[Unit] Description=IMAP Server Activation Socket Documentation=https://www.washington.edu/imap/ [Socket] ListenStream=0.0.0.0:993 Accept=true [Install] WantedBy=sockets.target
Also, a corresponding .service file needs to be created:
/etc/systemd/system/imaps@.service
[Unit] Description=IMAP Server [Service] ExecStart=-/usr/bin/imapd StandardInput=socket
UW-IMAPD uses PAM, so a PAM authorization file will also need to be created. This example will provide authentication using standard system passwords:
/etc/pam.d/imap
auth required pam_unix.so account required pam_unix.so session required pam_unix.so
SSL
A generic SSL certificate and key will be created at /etc/ssl/certs/imapd.pem if it does not yet exist. This can (and should) be replaced with a signed certificate for the specific server.
gollark: Wow, that sounds *intensely* trustworthy.
gollark: Interesting fact: Cap and WS is actually the only raider. They are trying to scam people into a "free Nitro" server.
gollark: I would trust them with SSH keys for a totally irrelevant system I don't care about.
gollark: They're so trustworthy that they're a Trusted User.
gollark: Factually incorrect.
