Description Henrik Krohns 2019-03-02 19:25:29 UTC

Refer from bug 7672

Atleast in the case of
Mail::SpamAssassin::Util::wrap($hdr, "\t", "", 79, 0, '(?<=[\s,])');

Multiple successive 79 char strings create blank lines in the output between them, which I think is not wanted. It seems code doesn't handle the case of multiple long strings. Needs some revamping and testing that fixing doesn't brake anything..

Created attachment 5669 [details]
A dummy message to reproduce the problem.

Possibly related to this bug report:

With the following in the config file:

    add_header all Relays-Untrusted _RELAYSUNTRUSTED_

the attached demo mail will produce a similar result, due to the very long hostname in the Received: header. I suspect it's the same problem.
