Unable to receive from one domain
in [Microsoft Exchange]
|
From: J on 19 Jan 2010 16:51 Hello, SBS 2003 with Exchange sp2. Unable to receive email from one domain (that I know of). We are on no BLs; we have rDNS in place. They receive no NDR. Problem domain uses St. Bernard for email filtering incoming and outgoing. SB sees the email sent to our email address and sees no issues. (To me, it seems like it could be dns resolution issue...maybe I should have asked SB to do an nslookup...forgot and now on hold again!) I don't see anything in the server log (I'm looking in C:\Program Files \Exchsrvr\SERVER.log and seeing other successful emails....please let me know if I should be looking somewhere else. I inherited this server and it is multi homed running RAS firewall. One NIC connnected to the router fromgroups.google.comocal network switch. I don't know if this could be blocking for some reason, but I don't see any indication of that. Any ideas appreciated.

Woops....sorry about all the dups...I was getting "server busy...try again in 30 secs" over and over
From: Ed Crowley [MVP] on 19 Jan 2010 18:34 What I would do is, from the sending domain's Exchange (or whatever) server, open a telnet session on port 25 to the mail host specified by your MX record and try sending a message. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." ..

From: Falcon ITS on 19 Jan 2010 21:50 Hello J, Have you checked Exchange message tracking ? Is the message entering the message tracking? Do you have third party spam filter? Do you have Exchange Filtering Set up? Connection Filtering, Intelligent Mesage Filtering? Is the sending domain's IP on any RBL's? Can the sender telnet on port 25 from their IP to your Exchange Server?

Have you enabled logging on the SMTP Virtual Server? The SMTP protocol log will show you whether you're receiving the message or not. --- Rich Matheisen MCSE+I, Exchange MVP
