Event 45824 SMTP
We have a new EV12 deployment. We have enabled SMTP journaling. It seems to be working but we're getting the following in the event logs:
The Enterprise Vault SMTP service rejected a connection.
The cause of problem is likely to be one of the following:
- An unauthorized computer is trying to connect to Enterprise Vault SMTP server.
- The remote computer trying to connect is a legitimate sender. But it has not been added to list of computers allowed to connect. Ensure that the remote computer has been added to the list of computers that are allowed to connect to Enterprise Vault SMTP servers.
- The Enterprise Vault SMTP server is either temporarily busy or it may have exceeded it maximum capacity for concurrent connections. Ensure that none of the SMTP servers are overloaded.
Internal Details: Reject - chan:<unknown> host:servername.domainname.com ip:::1 reason:E-MTA-NoInChannel No matching channel found for smtp
There isn't an EV12 specific article about this. I have increased the thread count and verified that the exchange servers are in the access control list. What's going on here?
The "solution" on this is a little weird.
I added the hostname of the EV server to the list of allowed computers for SMTP and the warnings went away. So there's some kind of recursion going on with SMTP.
I haven't heard back from support as to whether this is a supported solution.
