Another option, if you have a way of getting *every* SMTP address on your
SMTP server, is to programmatically build a sendmail "access" file every
half-an-hour or so.
There are various threads on this list dealing with using LDAP against
Microsoft Exchange servers to accomplish this - this is important since
Exchange doesn't work with md_check_against_smtp_server (always returns OK.)
Any new email address on your SMTP server will not be able to receive email
from the outside until the next scheduled "access" update - but this is not
generally a problem.
Basically it looks like this:
access:
[EMAIL PROTECTED] OK (or RELAY)
[EMAIL PROTECTED] OK (or RELAY)
...
@example.org REJECT (no unknown recipients @example.org please!)
Make sure to rehash access.db out of access once it's been built.
