A lot of "SPAM-BOTS" tries to send their payload to the MX with the highest "priority number". One why to avoid this is to make your primary MX Server have the highest AND lowest priority. This is for example what I have: dmj.nu MX 5 mail.dmj.nu. dmj.nu MX 10 collection.skandicinkasso.de. dmj.nu MX 20 mail.dmj.nu. I had the same problem as you when I only had MX5 & MX10. But after adding the MX20 I catch a lot of invalid spam mails. -- Dan Johansson, <http://www.dmj.nu> *************************************************** This message is printed on 100% recycled electrons! *************************************************** ------------------------------------------------------------------------------ _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
