OK, the do something like this: $origin city.wellington.net.nz. @ IN TXT "This domain does NOT accept mail" IN MX 5 fake fake IN A 10.99.98.97 That way - the remote end will not be able to deliver to you, nor will it loop at their end possibly breaking their stuff.
Agreed, it's just a pity that there is no way to flag the reverse case, when a host *does not* wish to receive mail under any circunstances, but still wants IP connectivity.
That above more or less does this, assuming remote admins are clueful and can drive dig.
In the circumstances, I think I'll just put up with breaking the RFC's for a while, at least until I get some SMTP filtering going to reject mail for city.wellington.net.nz as it arrives.
Its a qmail box - just use the anti-spam and not allow this site/domain. I'm really surprised is was killing the machine... qmail in no slouch, then again, you might be running solaris. If syslog is loading the box too much, try and turn of sync. log update to those files or log mail.* to /dev/null (evil). -cw --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
