email sent gets error "Receiving aborted by sender" ??

[newconcepts]

Hello and appreciate your feedback on this problem.

I am running qmail version 1.03, and Plesk version 8.3.1 and have a email verification system sending mail to an ISP using ironport.

The verification emails go through my email queue but the email server on the other side is getting the error "Receiving aborted by sender" and the mail does get delivered. Also there are no daemon errors nor a undlivered. The email seem to get lost completely.

These are the log errors they see on the IronPort X1050 mail appliances.

Any ideas where to look for the problem? Appreciate your posts.
