Hi All,
Greetings!
Our mail server configured Postfix version 2.4.5 with mailmarshal as content
filter, recently mail server not responding because of huge mail queue, content
filter cpu usage is 100%, my investigation found more than 18k mails are in
que, sender email address is m...@zbavitu.net
I have manually deleted mails in content filter queue and deferred mails in
mail server, now mail server functioning normally.
I wanted to investigate weather our mail server compromised or content filter
(windows machine) infected.
Please suggest methods to investigate so that will take precautions in future
the same will not repeat.
I would like to know how to load balancing mail server, due to above issue
mail server was down for 24 hours, we have secondary mx which queues mails when
primary mx is down, Is there any method where users can send or receive mails
from secondary mx when primary is down.
Thanks for suggestions.
Regards,
Ramesh
