Hi all!

I have some problem with connection to the sieve server;

----------------------------------------------

but connection to the sieve server should be ok;

root@test:~# telnet 127.0.0.1 2000
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
"IMPLEMENTATION" "Cyrus timsieved v2.2.13-Debian-2.2.13-19+squeeze3"
"SASL" "CRAM-MD5 PLAIN LOGIN NTLM DIGEST-MD5 GSSAPI"
"SIEVE" "fileinto reject envelope vacation imapflags notify subaddress relational comparator-i;ascii-numeric regex"
OK

Whats krb5.conf?

Thanks for any help!

Your sieve server offers GSSAPI and because this is the strongest authentication mechanism, open-xchange tries to use that (since it has kerberos support builtin. Just remove the package libsasl2-modules-gssapi-heimdal or libsasl2-modules-gssapi-mit, whatever you
have installed on your server running sieve, or configure your sieve server to only offer the PLAIN mechanism in capabilities.

Hi Carsten

Sorry for my late answer and thank a lot for your help. That was exactly my problem!

An how to get rid of the error without to disable GSSAPI? I am using GSSAPI when connecting to the server from another clients.
BTW: The fallback to another mechanizms worked before (don't remember in which version), but since some update it doesn't.

After update to 6.22 there is a com.openexchange.mail.filter.preferGSSAPI=false (default), which solves the problem for me.
