"Smtp server cannot be found"
Posted on 2006-05-08
'smtp server cannot be found' is the error I get when installing Outlook on my network. I can receive mail however. This is a small network of about 30 users. There are 3 stand-alone servers with one of them acting as dhcp and dns server for the network. The users are in one of 3 different workgroups. There are users in one workgroup who have Outlook running fine, but another group (mine) that gets the error message in question "smtp server cannot be found". I know the setup information in Outlook is correct cause I've used the same setup in a lot of other locations. I can ping my mail server ( eg. ping smtp.myservername.com) and the ping is successful and resolves the name to the ip address.
We do have a Sonicwall on the default gateway which is set to allow smtp traffiic to pass. But anyway, other users are successfully using Outlook on the network so it doesn't seem to be a router/port issue. Also I had a local smtp server set up on the network that I was using to send notifications of successful (or not) job completions using Veritas Backup Exec backup program. That was working fine for a while and then suddenly stopped. This prompted me to install Outlook because you can use a mapi client with the Veritas progam as well. But then I get the error, which again is saying that Outlook can't find my smtp server (smtp.myservername.com ). Any help or suggestions would be appreciated.
