5.08 and problems with Sieve/Dovecot

UCS - Univention Corporate Server
#1

Actually a Kopano mailserver is working in our domain (which isn’t supported in the future).

For tests I installed a new UCS server in the same domain (version 5.08) as a new Replica Directory Node and created the UCS Mailserver on it. No problems.

Test of port 4190 ok

# telnet localhost 4190
Trying ::1…
Trying 127.0.0.1…
Connected to localhost.
Escape character is ‘^]’.
“IMPLEMENTATION” “Dovecot (Debian) 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 imapflags notify”
“NOTIFY” “mailto”
“SASL” “PLAIN LOGIN”
“STARTTLS”
“VERSION” “1.0”
OK “Dovecot (Debian) ready.”

But Sieve/Dovecot accept not commands:

LISTSCRIPTS
NO “Error in MANAGESIEVE command received by server.”

NOR any authenfication commands

AUTHENTICATE … …
NO “Error in MANAGESIEVE command received by server.”

  1. Are there manual modifications in any conf-files of Dovocot or others neccessary ?
  2. Exist a web-gui for working with Sieve scripts in the UCS Mailserver (found only for Cyrrus or part of Groupware) ?

Thanks in advance …

I don’t think I can answer your question directly, but I am running Nextcloud on my UCS and the minimal sieve functionality in the Nextcloud mail client seems to be working. It looks like all it does is load the current user script and allow you to edit it and save it. Mine is currently the default script which moves spam to junk. I have used it in older version of Nextcloud to add a vacation message and that worked fine.

As far as I can recall I didn’t make any modifications to anything other than the user script, but I have upgrade through several versions of UCS and I did have Horde on my system under version 4 I think. It also worked with sieve.
