(Scrubbed) Re: filter by size of attachment

Yes, but my MTA won't allow me to create a whitelist like MailScanner does that will bypass that message size limitation.

In addition to all the other things MailScanner looks for, I'd like to be able to check for overly large messages. But, I have some customers who do not want  any filtering of anykind whatsoever on their messages. So, I just add their 'To:' addresses to the 'do not scan' whitelist in MailScanner, and they get what they want. This of course necessitates the message size check to be done in MailScanner, rather than the MTA.

Many of my dialup account customers have major problems in downloading emails that are over 2 meg in size; some have their client lockup, other think it locked up due to the time involved in the transfer and just abort.
