I rather use an event-driven than a periodically-run update. I wrote a bash script which is invoked on any delivering local MTA each time an account or alias is changed. The script collects all relevant information (domains, accounts, aliases) from all in-house MTA, and then sychronizes the data with sendmail's access, virtuser-domains, and virtusertable at the mailgateway. Local MTA's are qmail, Gateway-MTA is sendmail with MIMEDefang. Works perfectly here. The effect of this was a reduction of incoming mail traffic by 80% only by revoking wrong recipients during the envelope part of a SMTP session. The remaining 20% are then handled by MIMEDefang.
