Topic: Migration to iredmail
We are in the process of migration our old courier/exim/amavis/postgresql setup to iRedMail, which looks very promising. We have 150 domains hosted with only 3-10 accounts each. We have export/import working, but currenty have two issues.
The first is about recipient_delimiter i postfix. Our old system used "-" which allowed mail to user-random@domain to be delivered to user@domain. In iredmail and postfix the default is to use "+". Will anything break if we change that to "-"? The mailinglists maybe?
The second issue is about migration imap maildirs from courier to dovecot and roundcube. We do use the scripts from http://wiki.dovecot.org/Migration/Courier, and the maildirs seem to work from an imap client. But in roundcube no folders show up. Any expiernce with something like that or any hints at what we should look for?
