Email forwarding issue
I've been meaning to log on and say how much I love ISPConfig and how well it's working, but now I notice an issue.
I'm running ISPConfig 3.0.3 on Ubuntu. I recently set up email forwarding for a single email address on a single domain to come to my local ISP email address. I've never done this before.
If I send an email it takes about 2 days and then I get a "Mail System Error - Returned Mail" error with this message:
"Your message was not delivered because the destination computer was not reachable within the allowed queue period."
I really am a novice and don't know how to check Postfix for errors or even where to look for logs. I did some checking but can't figure it out for myseld.
Can anyone help?
