Hi!
We have a very severe problem: (first one is, that we are using a very old centos6 box and therefore an old amavis) Main problem: All incoming mails are received by postfix, checked by amavis&spamassassin and delivered to the internal exchange server that forwards it to Office365 Online Protection. All mails with dkim signatures do have valid signatures when checked by amavis but if amavis relais them to exchange (and O365 checks DKIM again) we get a dkim= fail (body hash did not verify) This happens anytime a german special char is in the email. Email without special chars have a working dkim body signature. And it is definitely amavis if I disable spamassassin or the anti virus agents the issues remain. If I disable amavis all mails got their dkim signature body hash intact CentOS version6 Amavisd-new 2.9.1-3.el6.noarch Does anyone has got an idea whats wrong?
