I am trying to install Dovecot on an Ubuntu server. For some reason, when I start the process, it informs me that the process is tunning, but when I search for it using "ps -A | grep dovecot", I see nothing, which leads me to think that for some reason it stops. The mail log tells me nothing.
I have a sneaking suspicion that I configured something wrong in my configuration file, but I can't manage to find the problem.
The configuration file is located at: dovecot.conf

According to the Dovecot mailing list, in version 1.2 of Dovecot login_greeting_capability was removed and is no longer needed.

I'm assuming it is erroring out because you are running v1.2 or newer.

Here's two quotes I found regarding this configuration setting:

 Send IMAP capabilities in greeting message. This makes it unnecessary for
 clients to request it with CAPABILITY command, so it saves one round-trip.
 Many clients however don't understand it and ask the CAPABILITY anyway.
 login_greeting_capability = no

"Removed login_greeting_capability. The capabilities are now always sent (Lemonade requires this and it's not that much extra traffic)."

wget http://www.loadingames.com/dovecot.conf
dovecot -F -c ./dovecot -n

tells me

Error: Error in configuration file ./dovecot.conf line 623: Unknown setting: login_greeting_capability

So you'd want to fix login_greeting_capability
