Using sendmail to redirect selected email

[Steven Schmidt]

Hi Mike,

Thanks for your reply.

On a per user basis.

The mailertable works fine for whole domains (The frontend serves many
domains) and individual redirects for single email addresses work fine, but
is not very scalable. (Can forsee a problem once many single redirects are
in the config and each sendmail process having to read through them every
time. CPU heaven)

Cheers
Steven Schmidt.
