Your mail system could not find a way to successfully communicate with the destination system. Please notify your administrator.
<FS-Mail.ERB.local #5.5.2 smtp;502 5.5.2 Error: command not recognized>
He was e-mailing user@eastriverbank.com
When looking at the mx record I saw the following.
5 smtp.perimeterco.com 63.76.208.166 86400
6 smtp2.perimeterco.com 63.76.208.238 86400
7 mailhost.eastriverbank.com 66.253.6.82 86400
10 mail28.ixwebhosting.com 76.162.254.116 86400
I tried telneting into each one to test but couldnt even get a helo response. The mailhost.eastriverbank.com doesnt even seem to exist.
Any and all help is appreciated.

can you try re-send? I just checked the mx records, at least the last one is accepting emails.

So it does appear that the top weighted 3 are not accepting e-mailsat this time correct? How did you verify that the last one is accepting at this time? And yes, I will ask the user to try again.

Thank you. Just a quick follow up question, it mentions that it may be greylisting, how does that effect my domain and the one your ran the test from and what does it mean?
