User Masquarading via pop

[Geoff Roberts]

Hi,

   Under sendmail I can setup a genericsdomain and genericstable to allow
me to do user masquarading:

mehere          [EMAIL PROTECTED]

   I can see how to do this when mailing from the Unix machine with qmail
on it (with the use of environment variables).

   But I would like all mail that goes into the ppp alias Maildir to have
the from field modified from [EMAIL PROTECTED] to [EMAIL PROTECTED]
Is there a way for this to happen for those that are connecting to qmail
via pop or imap?

   Thanks

   Geoff
