Hi All,
RFC, best practise etc etc aside for one moment, is there a way to stop exim generating bounce messages for a particular domain ?
We do backup MX for a couple of customers, who have their own Anti-Spam solution - using callouts (recipient verification), this works well until their Anti-Spam appliance generates a bounce after SMTP DATA (and actually in some RCPT TO instances) - in which case we then generate the bounce:
Ie:
2010-12-08 11:38:45 1PQIEA-0002tR-N2 ** user@??? R=dnslookup T=remote_smtp: SMTP error from remote mail server after RCPT TO:<user@???>: host spam appliance [1.1.1.1]: 550 5.5.0 <user@???>... no such recipient - user@???
2010-12-08 11:38:45 1PQIM9-0004Jz-5F <= <> R=1PQIEA-0002tR-N2 U=exim P=local S=8369
And
2010-12-08 09:21:50 1PQGDc-0000Jm-3j ** user2@??? R=dnslookup T=remote_smtp: SMTP error from remote mail server after end of data: host otherspamappliance [2.2.2.2]: 554 rejected due to spam content
2010-12-08 09:21:50 1PQGDe-0000OB-0a <= <> R=1PQGDc-0000Jm-3j U=exim P=local S=4609
2010-12-08 09:21:50 1PQGDc-0000Jm-3j Completed
I agree with comments related to: don't this is, against RFC's etc etc however this causing issues with various blacklists.. and the customer is adamant they wish to continue this.
So the question is, is there any option in the routers to stop bounces being generated ?
Thanks
Chris
