Is there a way via the address pattern to state .*@example\.com is

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)
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 [email protected], but also [email protected] or
[email protected]).
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).
In any case thanks for both answers - it worked ;)
That’s the main thing — happy to help! :-)
