[MlMt] exclude emails in address pattern ?

[Max Rydahl Andersen]

Hi,

I got a catch-all domain i.e @example.com
and thus I have address pattern set to `.*@example\.com` as illustrated
in
https://blog.freron.com/2013/handling-multiple-identities/

But I also have some aliases/forwards that aren't really mine for family
members,
lets say ***@example.com, ***@example.com, etc.

Those emails I really don't want to count as "me".

Is there a way via the address pattern to state .*@example\.com is good,
except ***@example.com and ***@example.com ?

Thanks,

If you can describe it with a regular expression, then you can put it
in. For example, you might be able to do something along the lines of:

.*(?<!dad|wife)@example\.com

For people not used to regular expressions, this uses so-called negative
lookbehind (if you want to google it). It is also possible to use
negative lookahead:

(?!(dad|wife)@).*@example\.com

That is (perhaps) a bit easier to read in this case. (I have not tested
it.)

mailmate uses PCRE-like syntax for its regular expression, right ? then
regextester.com is a nice tool for testing.

Then yours seems faulty: https://www.regextester.com/?fam=105641 (still
matches dad and wife).

but Davids (https://www.regextester.com/?fam=105642) seems more precise
(and actually seem to work for me in mailmate)

In any case thanks for both answers - it worked ;)

Not that it matters for you, but I'm pretty sure it works. MailMate uses
[oniguruma](https://github.com/kkos/oniguruma/blob/master/doc/RE) which
includes negative look-ahead.

Benny’s should actually be more precise — mine is vulnerable to
matching things that you might not want to exclude (e.g. it wouldn’t
just match ***@example.com, but also ***@example.com or
***@example.com).

But I would have thought Benny’s needs anchoring at the start of the
address in order to work as desired; maybe this is a difference with the
specific regular expression engine used in MailMate, but if you do
something like:

^(?!(dad|wife)@).*@example\.com


then I would expect it to work (and only filter out the specific
addresses listed in the bracketed part at the beginning).

That’s the main thing — happy to help! :-)

Actually, MailMate automatically adds anchoring to the address pattern
(`^...$`).
