rver. When a RCPT TO: is received, it's handed to the backend server. If it rejects it, PTSMTP sends the rejection reply back to the client and the message is never seen by PMAS (or PMDF). So using PMAS PTSMTP wouldn't change anything regarding those messages for bad usernames---they'd still be rejected during the SMTP session just as they are for you now.

I don't think our number is that high just yet, but I'm daily deleting close to 1,000 bounces to Postmaster because of bad usernames. > Is there any way around the processing for bad usernames? > -Rich David Webb wrote: > Note you can also get some of those benefits by using vfastscan > from eurokom (http://www.eurokom.ie/servMainSite?inner=vfastscan) We started using vFastScan a few years ago. Without some way of putting the virus defs into memory our Alpha would bog down in less than an hour and never catch up again, not even over the weekend. Not sure which method is cheaper or better, but vFastScan has been working for us, and we're still on the older version. -- Larry Wahlers Concordia Technologies The Lutheran Church - Missouri Synod mailto:larry.wahlers@concordiatech.org direct office line: (314) 996-1876 ================================================================================
