I just upgraded from 6.0.4 to 6.0.5 today on my Ubuntu 8.04 server. I was not expecting any important emails today, but a potential client decided to send one anyways. Regardless, they ended up contacting me at an alternate address (not on this server) saying that their email was getting bounced back to them. ...But they didnt say what they wanted to talk about. I'd really like to get their original email through soon.
I keep finding the excerpt below in my log files over and over again. And I need to know if it's because of the update, or because of some misconfiguration on my server or my SPF.
Prior to upgrading the server today. I had no issues receiving mail that I was aware of. This individual had never emailed me before today, so I don't know if it's something on their end or not. FYI their server appears to be a microsoft server, if it matters.
Also, the address of mine they are sending to is a Zimbra Persona, if that matters.
