Troubleshooting incoming mail problem with SBS 2011 standard exchange
Posted on 2013-12-01
No mail is coming into our sbs 2011 standard exchange server.
When I use mxtoolbox, to try to connect with SMTP, I get Failed to connect on the smtp connect test
I can log into the server with logmein, so it's up and there's internet access.
When I logged in tonight, it looks like it rebooted to install SBS 2011 SP1?
I rebooted the machine again, rebooted the watchguard firewall. The exchange services seem to be working.
Can someone give me some tips - how can I tell if I am getting through the firewall (port 25) / are the packets getting to the server or is the problem that exchange isn't accepting the mail?
How can I tell if port 25 didn't get closed down by the cable internet provider? (can I at least get to the firewall's wan port on port 25?
