If you provide remote SMTP access to roaming users, one problem is that users relay IP gets tagged in RBL tests like DYNABLOCK or NJABL_DAILUP. The solution depends on how you do things. I have a server that allows remote SMTP relaying for authorized users via a POP-before-SMTP scheme. I have a sendmail map of authorized IP's. In mimedefang, after I scan an email and give it a SA score, I then lower the score by 4.0 if the relay IP exists in my sendmail map of IP's allowed to relay. I still filter outbound mail because I don't want my users sending spam. By simply lowering their score by 4.0 I can still catch some really bad stuff.
Likewise, you still want to filter outbound mail for viruses too, as you dont want to be blamed for causing issues that your users created! -John ---------------------------------------------------- >From : Rob <[EMAIL PROTECTED]> To : <[EMAIL PROTECTED]> Subject : RE: [Mimedefang] Outbound messages are blocked Date : Tue, 6 Jul 2004 17:23:14 +0100 > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] On > > Behalf Of Vivek Kumar > > > > Some of the outbound messages are getting blocked and sent to spamdrop > > account. > > > > How can I stop it ??
