Server 10.3.8, squirrelmail, cyrus, postfix, timsieved, Avelsieve etc. as discussed and recommended here. Have goggled for answers to the problem below, but did not find anything.
If anyone else has experienced this problem, and/or has other suggestions I can try, I would appreciate any help.
When using MSIE and Squirrelmail every time a message is sent,
an error dialog pops up:
Security Error: Data Decryption Error
Same with Netscape gives
The connection to [myserver FQDN]:16080 has terminated unexpectedly. Some data may have been transferred.
Safari does not show anything.
For all three browsers, the Compose page stays on, it is never exited. The mail is delivered but it is confusing for the users, and they don’t trust it. IMAP works like a charm, BTW.
If I turn off Web Performance Cache in Apache the same thing happens, only at port 80 in Netscape.
There are no firewalls involved on the server, on the clients or between them.
What to to, where to start?
TIA,
Peter
