Changing webmail, from Roundcube to SnappyMail

We’re changing our webmail program, and it’s now SnappyMail

Access to our webmail can be done trough the following link.

I was prompted to investigate why it was impossible to use the old webmail trough a ticket on our helpdesk, and the issue is that mail.tilde.green was pointing to a localhost IP and at some point that /etc/hosts entry was commented out, so webmail stopped being able to talk to dovecot which is weird because dovecot is bound to the IP, but not accepting connections from the box itself but from other sites on the internet the same IP/port is reachable.

The solution is to use the IP I probably bound it for directly, since we’re not doing TLS, even if we should probably enable that for the local transit between the box and itself.

I wouldn’t have needed to change the webmail program from Roundcube, but I did, because SnappyMail makes it easy to handle multiple domains going to different servers, and the configuration is editable via a WebUI rather than in a php file, and having to regenerate a table if you touch a few specific settings. The latter of problems which has bugged me a few times, and required me to manually edit a MySQL table so the username looks properly, which was a PITA.

Dovecot among other IPs binds to 127.0.210.15, and that’s the IP to which SnappyMail will connect to do IMAP, SMTP, and Sieve.
