Greetings,
I propose that the problem would be solved simply by the SG code adding the Cc: field to the fields that the exclusive sender regex matches against.
If I understand correctly, currently the SG code matches only against the two fields From: and To:
Is there any technical reason not to match against the Cc: field?
SG does not have to match against all sorts of weird mail header fields.
In my experience people use practically only From:, To:, and Cc: when they compose their mailing list answers.
The point is that Cc: is being used quite often.
With regards to the single dot (".") proposal; I do not consider myself a PCRE ninja, but would a single dot not just match a single character?
If you mean ".*", I have read that that is computationally heavy, and therefore should not be used.
Finally, I seem to not be the only one missing Cc: support in the exclusive sender regex:
https://bbs.spamgourmet.com/viewtopic.php?t=1301That use case is slightly different from mine though, as my use case has a non-SG address in the To: field, whereas the other use case has an SG address in the To: field.
However, it seems to me that both use cases would be acommodated simply by SG supporting the Cc: field in the exclusive sender regex.
Best regards
Johnny
