Hello all, new happy Enhance user here. I have question. Does sieve and mail filtering works on Enhance as it should work? I see a lot of error messages in mail error log, so before i dig deeper, is that normal (!?) or something is not right on my server and there is known workaround for it?

root@lin1:/var/log# tail -f mail.err

However:

root@lin1:~# telnet localhost 4190
Trying ::1...
Connected to localhost.
Escape character is '^]'.
"IMPLEMENTATION" "Dovecot (Ubuntu) Pigeonhole"
"SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext imapsieve vnd.dovecot.imapsieve"
"NOTIFY" "mailto"
"SASL" "PLAIN LOGIN"
"STARTTLS"
"VERSION" "1.0"
OK "Dovecot (Ubuntu) ready."

But those error messages above, looks like it is started, it is working ( service ), but it does nothing, sine per domain rules are either wrong, or not set up correctly.

What am I missing?
