Dear all,
In my organization I must configure Exim to add a disclaimer for every
outgoing email, both text and html.
Please do not argue that this should not be done blablabla... I have to
do this for administrative reasons, too long to explain and off topic.
I am doing something similar, and am not seeing widespread DKIM
refusals. I have not used altermime.
Be aware that exim filter wants line endings as \n not as \r\n
I suggest wrapping the filter in a script and have the script save
before and after versions of the filtered email (eg: use tee),
and then check those for basic validity, especially line endings.
Dear Jasen,
The altermime filter does the job well with Exim, as long as I do not use
DKIM. So I do not think the issue is there.
I se that you have set dmarc to do 'strict' checking; if you changed
to relaxed checking with
adkim=r
the line endings that Jasen mentioned would be ignored:
# host -t txt _dmarc.abcreseau.com
_dmarc.abcreseau.com descriptive text
"v=DMARC1; p=reject; adkim=s; aspf=s; rua=mailto:[email protected] "
