Repost from this post in the SpamBlocker4 sub-forum since this doesn't actually seem related specifically to that SpamBlocker4 version after all.
After updating Exim itself from the stock Debian 6 da_exim-4.73 to exim-4.84, installed with CB 2.0 and updating exim.conf to the latest stable 4.2.2 and exim.pl to 17. We noticed it looks like it has some problems to verify local email addresses for external smtp hosts. As we're getting quite a lot of errors like these:
This might have something to do with the fact this domain has a catchall email configuration so the email address testemail@prism.nl can't be found in the list of virtual emails for this domain, however since it does have a catchall it should still verify the email address back to the smtp host since it is a valid email address.
This specific email did eventually go out after I created a forwarder testemail@prism.nl -> catchallemailaccount23@prism.nl (the normal catchall email address). After that the "451 <testemail@prism.nl> unable to verify address" stopped and the email was delivered at Telefonica. So maybe this is still a problem with the exim conf not verifying email accounts in case of a catchall, any ideas?
