It sounds like an AVG problem. There is no requirement that SMTP submission always work, so if your email client can't handle an error it suggests it is broken. I'm not sure working around failure to handle error conditions is the smart approach, as your users will then silently lose email when a different error condition arises. My email client says "I'll leave it in the outbox till you fix it" when this occurs.
