Hi,
My previous ISP had this recipe for forwarding virtual email aliases
to real email accounts. However, lately I've been reading in the
manuals and on this mailing list that it's a "losing battle"....
Here is their recipe: The only problem I had with it was with
mailing lists, when the recipient email is somehwere in a "for
alias(_at_)thisdomain(_dot_)com". Of course it didn't catch those because the
recipes don't use the built in ^TO_ or ^TO (would those catch a 'for'
?).
Anyway, here is their recipe... with the ISP annotations. I would
appreciate if someone could evaluate this 'solution' and point out
what could be wrong.
[...]
This approach has the same problems the initial poster was trying
to solve: it doesn't handle "Bcc:"s and messages received from mailing
lists. This happens because the envelope recipients are lost at the
time the message is "seen" by Procmail, and there's no reliable way to
recover them. That information is not present in the headers, period.
Like I said, the right way to handle this is to add MTA aliases for
the relevant addresses.

Liviu Daia
