Can I process user's outgoing mail?
For example:
I need to save a copy of sent mails from some users.
Is it posible with sendmail??
I think the solution in the archives and the FAQ recommend wrapping
the sendmail binary on your machines. Then when the MUA invokes sendmail,
it's actually invoking a script that pumps the message through procmail
*AND* sendmail.
Of course, this design is flawed if you connect directly to the SMTP
port for some reason or other (i.e. POP) or if other sites use you as
their "Smart" host.
A better solution is what I've done in the past -- patch deliver.c in
sendmail. You'll want to make some checks to make sure that the mail
originated from certain domains, but in essence you're just adding a
local address to the recipient list. That address can be an actual user
account or an alias that opens a pipe to procmail.
