Emails Are Getting Rejected by Bounce Verification We Use IronPort
I have an issue sending email to one domain. We get the message(s) depending on if we disable Bounce Verification on our IronPort or not.
Before Disabling Bounce Verification on Our End
Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:
user@recipient.com on 11/06/2008 17:01
The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.
< mail-ip-in.mydomain.co.uk #5.0.0 smtp; 5.1.0 - Unknown address error 550-'Verification failed for <user@mydomain.co.uk>\nPre
When I disable Bounce Verification, we get:

It looks as it is a bounce verification issue together with sender base verification. If bounce verfication is in effect, all e-mail that is sent through the ironport towards the outside is tagged in the FROM envelope.
That is, the envelope address changes from "test@my.domain" to something like "prvs=test=26654df9b@my.do
