Hi Alexander
[root@maui:/var/log]$ watch 'tail -n40 maillog
does not quiver when I try to connect
That's suspicious.
Let's exclude it is the client which causes the problem: Connect directly
to the IMAPS server on CLI.
openssl s_client -connect <server ip>:993
You hopefully see a greeting message from the IMAP server. Then issue
a1 LOGIN username password
If you see a success message that you logged in, then everything is fine
with your cyrus-imapd.
Logout by entering
a2 LOGOUT
If you got that far, the troublemaker is Evolution. Can't help you with
that one as I am not using it. Validate all the account settings to be
valid.
In coming mail can be seen but nothing about evo connections as far as I
can see
There do seem to be some warnings/errors - they don't look relavant??
Right, irrelevant for your isse.
Many thanks for your help
John
You really should see your user login in this log file.

Hmmm

A little more info about using s_client on paxos to connect to maui
openssl s_client -connect maui.jaa.org.uk:993
Wireshark shows just one packet each way (to/from port 993)
A request for connection from paxos to maui and a reset from maui to paxos
