[Dovecot] dovecot 2.1.1 + pigeonhole + avelsieve

[Frank Elsner]

Hello all,

I've squirrelmail-webmail-1.4.22, dovecot 2.1.1, dovecot-2.1-pigeonhole-0.3.0 
installed and working. But I've problems to get the avelsieve plugin for 
squirrelmail working with dovecot.

The "Message Filters" show up in "Options" of squirrelmail, but 
"Could not log on to timsieved daemon on your IMAP server ........."

dovecot log shows:

Mar  6 00:00:47 seymour dovecot: managesieve-login: Disconnected: Too many invalid commands. (no auth attempts in 0 secs): 192.168.28.53, secured

Where to look for configuration error(s)?

Ok, looking forward for any tip,
