2017-01-23 In July last year, I already had a problem with mails without a body (i.e. only headers, which is valid according to RFC 822), causing problems. [0] I posted the problem on the qpsmtpd mailing list, [1] where (after some messages back and forth) Charlie Brady pointed me [2] to this bugreport. [3] (The problem is an old one. [4] ) I did not manage to apply the there linked patch [5] until today, when Bryton Hall had problems subscribing to the mmh mailing list, caused by an empty message body. He took some initiative, which motivated me to finally solve the problem by applying the patch.
