Hi
Normally WinGate would keep trying the rest of the messages for that domain job, so I'm wondering how that message is being blocked that is preventing this.
if you turn on debug logging in the SMTP delivery service, and try forcing send of that job, you should get a transcript of everything going on. If that doesn't make the problem clear, post the log info here or to our support desk (
support@wingate.com) and we can take it further.
