hello, You can check your watchguard logs from your logging/management station to see if there are any blocked packets going to your server's port 25. It may also be a DNS issue if your exchange box cannot resolve other domains/servers, but unlikely though.
alternatively, you can post your logs here for us to see and advise. Best of luck, Paul Tan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Katie Kuehn Sent: Thursday, January 17, 2002 12:42 AM To: '[EMAIL PROTECTED]' Subject: Communications failure after installing Watchguard I recently installed a Watchguard Firebox. Originally, it appeared that all mail from my Exchange 5.5 server was sending and receiving to all types of mailservers. Come to find out that there are two mail servers in the building right next door to us that we are unable to send mail to or receive mail from. My mail server is mail.esp.fsu.edu The first mail server, an Exchange box, that I tried sending to was titus.cefa.fsu.edu with no result, they are not able to send mail to us either. The other is a Linus box running Send Mail, named odie.ispa.fsu.edu in the same building cannot send mail to us or receive mail from us. I have confirmed that they are able to send/receive from all types of mail servers also. We just are not communicating with one another. I have gotten two different messages, which I have confirmed that they have gotten as well, they follow: -----Original Message----- > From: System Administrator > Sent: Sunday, January 13, 2002 2:38 PM > To: '[EMAIL PROTECTED]' > Subject: Undeliverable: test > > Your message did not reach some or all of the intended recipients. > > Subject: test > Sent: 1/11/2002 2:37 PM > > The following recipient(s) could not be reached: > > '[EMAIL PROTECTED]' on 1/13/2002 2:38 PM > The recipient was unavailable to take delivery of the message > The MTS-ID of the original message is: c=US;a= > ;p=CITES;l=MAIL-020111193631Z-640 > MSEXCH:IMS:CITES:FSU:MAIL 3499 (000B09AA) Host unreachable > Your message To: Teresa; Swickleys; Dina Davis; Denise Subject: Fw: THE BEST IDEA SINCE SLICED BREAD Sent: Wed, 16 Jan 2002 08:43:51 -0500 did not reach the following recipient(s): Denise on Wed, 16 Jan 2002 08:57:09 -0500 Unable to deliver the message due to a communications failure The MTS-ID of the original message is: c=us;a= ;p=cites;l=MAIL0201161356DAN0HCW8 MSEXCH:IMS:CITES:FSU:MAIL 3554 (000B09AA) 554 Invalid data in message They also received the following error on their Linux server after holding it for 5 days: ---------- Forwarded message ---------- Date: Mon, 14 Jan 2002 09:14:09 -0500 From: j. mac hall <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Fwd: Returned mail: see transcript for details >Date: Sat, 12 Jan 2002 11:57:29 -0500 >From: Mail Delivery Subsystem <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Subject: Returned mail: see transcript for details >Auto-Submitted: auto-generated (failure) > >The original message was received at Mon, 7 Jan 2002 11:57:15 -0500 >from constantine.ispa.fsu.edu [146.201.211.90] > > ----- The following addresses had permanent fatal errors ----- ><[EMAIL PROTECTED]> > (reason: ) > > ----- Transcript of session follows ----- ><[EMAIL PROTECTED]>...
