Re: The Old 530 5.7.1 Error Redux ...

One final post (for now, anyway) just in case someone else runs across this. I installed Zimbra 8.6 on a spare machine today and played with it. First, without a relayhost in postfix/conf/main.cf, I was able to send email to the outside world just fine. I then went into Zimbra Admin, added the IP ad...

Re: The Old 530 5.7.1 Error Redux ...

Thanks, Bill. I'm going to check a couple of other things later today. I *think* what is happening is that the MTA Relay field in the postfix configuration is not being cleared to a blank string, even though it has been set to the blank string in Zimbra Admin. I'm going to look into that. If that's ...

Re: The Old 530 5.7.1 Error Redux ...

OH-KAY: A bit more info. Tonight, I set up our pfsense firewall to do a packet capture on anything headed to the IP address of the spam filter of my personal ISP (hiwaay.net, their mail is handled by antespam.com). With Barracuda inline, everything worked fine, as mentioned above. I bypassed Barracu...

Re: The Old 530 5.7.1 Error Redux ...

A brief update: one of the ISPs that was rejecting our email was Hiwaay in Alabama. I'm friends with those guys and had one of their techs pull up the logs to see if he saw anything. He says, "nada." Nothing. This is truly baffling. It's also concerning that other, similar posts to mine --...

The Old 530 5.7.1 Error Redux ...

The closest I've seen to our issue, after lots of Googlin' and searchin', is this discussion here: https://forums.zimbra.org/viewtopic.php?f=15&t=63617&p=281610&hilit=530+5.7.1#p281610 . Not quite the same, but I'll carefully pore through that one tonight. Our setup is Zimbra 8.6 running...

Re: Barracuda passes the email, Zimbra drops it

The plot thickens. I probably should have given this example, rather than the one above. Note that the indeed.com email goes to one user just fine, but is rejected for another. zimbra.log-20171014:Oct 13 07:42:11 mail postfix/qmgr[16269]: 2BDA13502BF1: from=<bounce+980268.611b4-user1=wdjconline.com@...

Barracuda passes the email, Zimbra drops it

This is a good one. I've been tinkering with this for a couple of days. I'm running Zimbra 8.7 Community Edition on CentOS 6.9. Here's the most important thing: my setup has been working splendidly for over a year. I haven't changed anything in the config. This is a RECENT problem. I have disabled S...

Deleted Account Still Sending SPAM?

Woke up this morning to discover that our mail server (Zimbra 8.6 running on CentOS 6.7) has been placed on several blacklists. After a bit of research, I discovered that one of our users was apparently spamming like mad. I disabled the account, then deleted it entirely. In Zimbra Admin, in the Moni...
