you r da man till!
yes i tested and it works fine
the only discrepency i found is regarding catch-alls
if i have a mailbox "email@example.com"
with a catchall setup @domain.com => firstname.lastname@example.org
and i make an archive mailbox "email@example.com"
and then add the "cc "!firstname.lastname@example.org"" to custom rules (while leaving everything else there)
it will wipe out the catchall (in the list view it shows @domain.com => blank)
all i needed to do was add the custom rule, THEN re-add the catchall and it is all working
will this break with a config file update though? the catch-all is much more important than the archiving tbh (and yes, i know catch alls are very bad, but for this particular domain it avoids MUCH mess)
