Exchange 2010 -connection timed out -telnet port 25
We've been running our current exchange 2010 server for about 9 months now and every thing has been working fine. But, today all of our multi-function printers that are set up to scan to email are no longer able to send emails.
Nothing has changed on the mail server or the scanners. It just stopped working for no obvious reason. Our mailserver still works as expected. We can send emails internally and externally. Outlook and OWA work properly. It's just the scanners that give me the error "Transmit/Receive Error (0x3101)".
They are sending emails without authentication. There is a receive connector that allows their IP addresses to send emails without authentication.
I figured that I would try and send an email through the exchange server with telnet on port 25. But when I try it just says Connection timed out as soon as I type EHLO or HELO.
Any ideas about what's going on?

You're a life saver! Thanks so much. Our 90 GB database was taking up 270GB of space on the server and we were out of room. I turned on circular logging and it dropped back down to a reasonable size in a minute or so.
Is there a reason why I wouldn't want to just leave circular logging on?

Depends on how often you backup with an Exchange Aware backup program.
Without logfiles to replay, if you need to restore from backup, you will lose something if you don't backup regularly.

I do not know all of the providers who do this so if yours is not listed here you may want to reach out to them and ask - asking the question doesn't hurt.
If they blocked port 25 then this would be your issue.
