I have some users configured in Exchange 2003 (delivery options tab) to forward mails to their external address.
This was working fine until today. The mails are being held up in the SMTP queue folder. I am able telnet the addresses (e.g. google.com) at port 25 from the server. Any reason why the mails are held up? Other emails are going out. It's only the mailboxes configured to forward the mail out to the public email addresses.
I also did the following
- Check event logs for errors. Nothing.
- Checked my domain on blacklists. Nothing.
