Ok, i'm fairly savvy in linux etc, but i'm getting these messages from various domains from time to time in regards to rockettheme.com email:
Remote host said: 451 Could not complete sender verify callout
Now, as I understand it, this is as a result of the receipients email server calling back to rockettheme to verify the address (This email address is being protected from spambots. You need JavaScript enabled to view it.) as I understand it. I'm running Plesk and i'm pretty sure its qmail underneath. Any ideas of there is some config options i should be setting?

Thanks for the link, but the problem i have is other SMTP servers saying that rockettheme is not implementing callout verify, it's not my server that's doing it. It's the other way around from this post.
cheers,

Andy...
I'm not a Linux Guru, but I did spend the night at a Holiday Express.
I am 'familiar' with Linux...some of the first webservers I ran were "RAQs" and "CUBEs", but being from Georgia.... I know more about "Lennox Square" than "Linux Squares".
But... your issue is with email...so, this may help you figure it out.
Go here : www.dnsreport.com/tools/dnsreport.ch?domain=rockettheme.com
Once the page loads, you will see several issues. Yellow blocks are 'warnings' and 'red' are failures. HOWEVER... I have seen 'failures and warnings' being generated that were false.
Anyway... you will see an area concerning MX records...towards the bottom. One of the warning is:WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record.
mail.rockettheme.com claims to be host rockettheme.com [but that host is at 69.64.38.246 (may be cached), not 69.64.36.31].
IF I were troubleshooting this, I would start with clearing up all of the warnings and failures on my end, THAT I KNEW WERE VALID....and then start looking at other things.
