The only way to be sure is to inspect the message after they went through
a hop and compare them with the originally sent message. Use the "hold" action to capture the mail and have a look at it with "postcat -q queue-id". That way you can compare the mail before and after it went through Amavisd-new.
I wasn't sure how to do that, but I thought of an easy test. I tried it without discarding the 8bitmime, which caused the message to bounce again. I then disabled the antivirus checking. Tried the message again, and it went through, so it was amavis changing the message to 8 bit. I then downloaded 2.4.5 and rebuilt it and installed it. Turned the antivirus scanning back on, and the message went through again. I saw this in the release notes - prefer '7bit' as Content-Transfer-Encoding when attaching original message or its headers (message/rfc822 or text/rfc822-headers) to DSN or to a defanged mail, and only specify '8bit' when necessary; So I don't know if it was a known problem or not, but I do know it is now working without discarding the 8bitmime.
I am not an expert on mime encapsulation but AFAIK every mime entity can have a different encoding. If you are using AlterMIME to add Footers to outgoing mails or something similar, that could also introduce 8bitmime.
I saw something about that as well in the release notes, but I don't use that. So thanks once again. Your help was invaluable in tracking this down at least to the source of the conversion, which was the point causing me the most confusion. I couldn't figure out that while the reports I found on the bounce messages pointed to an 8bitmime problem, I was sending a 7 bit message and shouldn't have been affected. I will file a bug report on amavisd-new, but realize since Postfix works correctly when connecting to a server that does not advertise 8bitmime, this would only show up in a situation like mine.
