I'm running MailEnable on my server, and have been for many years. Recently we had an attack on our server, and I was able to close the hole.
Since then, our
mail server doesn't seem to be sending
mail out.
If I send an email from myself to another account hosted on the server, the email arrives as expected.
If I send an email from my gmail account to my business account, the email also arrives as expected
The problem comes when I send from my business account to an external domain
I tried the following
Gmail.com
Hotmail.com
Shaw.ca
When I send to any of the above
The message leaves my client as expected,
The logs appear to accept and forward on the message
The SMTP outbound que is empty
The message never arrives
I have checked our domain with
mxtoolbox.com
senderbase.org
And neither of them are reporting any problems with our domain.
I have ensured that port 25 is open (along with the other standard ports)
Here is one of the log entries from the SMTP connector

Where else can I check to see if there is something broken? What could cause a problem like this whereby the message appears to send, but never arrives, and never returns a bounce?
