Check to see if the events occur only when sending to a specific host or domain. I also agree that it's not your NAT router.ġ003,SMTP Relay,Warning,Normal,An unexpected IO error condition occurred on an outbound connection.,May indicate a problem with a remote host. Has anyone encountered this problem before? And do you have a solution that works? Tech support from Linksys has been just as useless - they claim that if you set the Filtering tab for the router for E-mail application outgoing 25 and incoming 110 that everything should work otherwise play with the MTU settings until it works. their web site is even worse.) At the very least they confirmed that the server settings are ok and the connection should be working. They claim if the connection works when you directly connect to the phone line (DSL) then the problem is not with their set up but with the router. Tech support from Sypatico has not been useful.

But the problem now is affecting both my own messages as well as forwarded email.Įrror: 'Your email message to with the subject was unable to be sent.' (1003,9) The problem seems to have developed recently and is finally getting to be a great pain.Īnd it appears to happen more often when I'm forwarding email to someone else then when I create a message myself.

I appear to be having a problem sending email through to my SMTP mail server.
