I an using an external service as an email backup in case my server goes down. Unfortunately, I am running into a problem with qmail-scanner rejecting anything coming from this server as it is looking like a relay. Some of the email is spam but others are legitimate and it seems that everything is getting rejected. The error on their end is the following:
Malformed SMTP reply from mail.xxxx.com [xx.xx.xx.xx]
in response to end of data: X-Qmail-Scanner-2.02st: We have reasons to
believe this mail is SPAM (#5.7.1)
I have white listed the domain in local.cf. I also understand that there is no way to whitelist for qmail-scanner. Any suggestions?
Thanks
