Hello,

I started having email problems where even internal
emails don't get delivered unless I restart the SMTP
service.

I am looking at the Exchange System Manager,
Servers, <ServerName>, Queues and I see
two high numbers:

DSN messages pending submission (Protocol SMTP)
Number of messages : 625

Messages pending submission (Protocol SMTP)
Number of messages : 5,211

What are these messages? Why they are not finishing?
What can I do to find out more info or fix this problem?

I see a lot of EventID 7010 in the log but I checked this
error is OK as it says that SMTP Relaying was blocked.
So I guess anti-relaying is configured and working fine, then
what could be the cause of 5,211 messages? And the number
is going up.

And under Protocols, SMTP, Default SMTP, Current Sessions,
is it normal i see some sessions and 1 session reaching 300
seconds of Connected Time? It is not my ISP so who is connecting for
this long? Is this a vulnerability/hole on my Exchange that is allowing
someone to be connected this long?

I would appreciate any help.

Thank you
