[vps-mail] Editable .procmailrc or blacklist

[Blarneystone Maillists <maillists@xxxxxxxxxxxxxxxx>]

I have a client on a shared vps2 wanting to blacklist his email by subject.
I know the SA filter via iManager filters by blacklist_from and _to but can
it do anything like blacklist_subject? If not, is there an easy way for an
end user to edit their .procmailrc file without breaching security for other
areas? He isn't a novice user so I'm not worried about him messing up his
.procmailrc file but since my clients usually don't want to do things like
that themselves, I've never bothered figuring out whether that is an option.

Alternative suggestions are welcome as well.

Regards,

Jim Smith
