does MailScanner use port 587?

[Jeff A. Earickson]

Julian,

A brain cramp here...  Does it make any difference to MailScanner
if sendmail listens on both ports 25 and 587?  Does MailScanner
treat email via 587 any differently than email from port 25?
Advice on using port 587 (or not) please?

The flow is sendmail-in -> MailScanner -> sendmail -> delivery,
so I wouldn't think that port numbers would matter, right?
