I have been using __MANY_RECIPS in some meta rules for some time now,
and noticed a weird FP today. The rule seems to count the number of '@'s
in the To and CC header. Someone sent a mail to using the (albeit silly)
format, probably by using reply-to-all in a braindead MUA:
To The foo mailing list f...@lists.domain.tld
CC: f...@lists.domain.tld f...@lists.domain.tld
This triggers the __MANY_RECIPS rule as the @ occurs (at least?) 3 times.
Is there any alternative to this rule, that only lists the addresses
(i.e. excludes the name part in the To/CC)?
Nothing even remotely correct and sufficiently simple to squeeze into a
RE. Counting the @ chars is pretty rough, but a suitable trade-off IMHO.
I'd argue that 3 is too low to count as many. (Regardless of the
implementation and the FP you encountered.)
Or maybe even removes the duplicates (that would probably be an eval
rule)?
Yep, that would require an eval rule. As would any more sophisticate
implementation of the original rule.
