[Annoyed] Cyrus-imapd/sasl upgrade and lmtpd behaviour...

[Steve Clement]

Hi,

first off all I want to say hello to the list as I am new on it. Small 
and boring intro:
I am a Unix Sysadmin from Luxembourg and in constant fight with lmtpd 
when it comes to updates :(

following stuff has been updated:

cyrus-sasl/imapd-2.1.5 -> cyrus-imapd-2.1.11 sasl-2.1.10

I used the very same configure lines as before all worked allright but 
when I restarted the 'master ' program I saw this entry in the logs:

iron deliver[15406]: connect(/var/imap/socket/lmtp) failed: Connection 
refused

This is really annoying and now my live servers are fucked, so no mail 
for me anymore nor for my clients. Obvious question: what changed/have I 
done wrong?

Now my cyrus.conf file might not be really up to date as the ctl_deliver 
is deprecated, but that aint the problem.
I remember having this problem before but I can't remember how I fixed 
it. But I do remember it took days to figure out.

Find attached my 2 conf files.

If you guys can't help please point me too some other place as this is 
really urgent.

Thank you all very much in advance,

Steve
