Hi,

I've just rolled out 4.93 from sources on Devuan - all working fine,
no problems.

In the process of checking everything is OK I noticed rejects of the
form :-

2020-02-23 16:35:12 1j5uDo-0002yt-Ig H=(NN.NN.NN.NN.example.org) \
    [NN.NN.NN.NN] F=<User@???> rejected after DATA: \
    header syntax (unqualified address not permitted: failing \
    address in "From:" header is: =?utf-8?B?UTFENCODEDSTRING+?=): \
    unqualified address not permitted: failing address in \
    "From:" header is: =?utf-8?B?UTFENCODEDSTRING+?=


Excuse the obfuscation.

I've never noticed these before but when I look back in the logs they
have been happening forever and nobody's complained :-)

When I unpick the actual UTFENCOIDEDSTRING I get what I would call a
fairly normal address list of the form :-

NAME <user@???>.

These messages are occurring for other headers, e.g. Reply-To.

I had a look at RFC 2822 and NAME <user@???> does seem to be a
valid value for these headers.

Is exim just rejecting them because they are utf-8 encoded ?

I'm not bothered about them being rejected BTW - I can't find any
legitimate senders.


TTFN
