Fact

I switched my IMAP server from Courier to Dovecot.

Reason

I was never really fond of Courier. It is a capable but cumbersome system.
Since “everybody” was talking about Dovecot and it was made the default IMAP server for various systems, I decided to try it myself.

Process

Quite easy.

• Install with Apt.
• Create the database user for Dovecot.
• Fiddle with the SQL configuration (don’t forget to uncomment the sql section in dovecot.conf).
• Fiddle with the directory settings (it still does not take individual mail directories from the database).
• Change my password in the database (very easy with dovecotpw).
• Reindex my mails with Thunderbird.

Result

😀
