Using sendmail to redirect selected email

[Steven Schmidt]

Hi All,

I have a bit of a scaling problem.

Senario.
Frontend box running Sendmail which redirects email traffic for selected
customers to a box running MailScanner.
MailScanner does the Spam/Virus check, then forwards to final maildrop.
For non-selected customers, it forwards the mail though to the final
maildrop directly.
I am using a redirect statement for each redirect customer in sendmail
config to redirect selected email. Works fine but is not very scalable.
(Works fine for a couple of thousand, but if I want to go any higher, will
need to change the way I'm doing it)

Anybody else using sendmail to decide who gets scanned and who doesn't.  Any
ideas would be appreciated.
(Have been considering qmail, but this would require major changes to the
frontend)

Regards
Steven Schmidt.
