[Dovecot] Dovecot LDA

I have it working now, it wasn't working because the parent directory of 
auth_master didn't exist. I modified the wiki to include that this path has 
to exist and is not created automatically (ie: /var/run/dovecot).

Another question to which I couldn't find the answer in the wiki is whether 
'lda' should be added to the protocols line in the configuration, such that 
it becomes:

protocols pop3 pop3s imap imaps lda
