For several months I have been searching the reason for a 25 seconds
delay on every Squirrelmail operation (login, select folder, select
another page) - the mail server runs on FreeBSD 6.x with latest
postfix and Cyrus IMAP with Cyrus SASL authentication against a
Mail clients like Mac Mail, Thunderbird, etc. do not exhibit this
I received some guidance on this list and I tried quite a few things
without being able to locate the problem.
Today, however, I finally noticed something -
1. All operations that I could try using imtest respond immediately
(including initial login).
2. However the initial login of cyradm is delayed exactly 25 seconds.
It would be great if someone could help me analyze the reason for this
difference, which might bring me closer to the issue.
Cyrus does not have redundant authentication mechanisms (some people
suggested that this might cause delay) and the 25 seconds appear very
stable (i. e. it is always 25 seconds).
Thank you very much!
