Re: Is this a problem with my email server or the recipients's?

There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.

<SERVER.Company.com #5.5.0 smtp;550 Denied by policy.>

One person in our company will get this iintermittently when she emails anyone at a county government. Does this reflect a problem at the recipient's email server or mine?


Could be either; telnet to both your server and the remote server (to get the mx, do nslookup -q=MX domain.name and choose the lowest cost MX). have a conversation:

EHLO yourdomain.com
MAIL FROM:<that.user@xxxxxxxxxxxxxxx>
RCPT TO:<the.recipient@xxxxxxxxxxxxxxx>
DATA
Testing - please disregard this message.

..

the <enter> period <enter> at the end is what signals the mailserver. this might not work, since you said it was intermittent, but it is worth a shot. Check your policies - if you have none, then chances are it's them. You can always call their mail admin and ask, i suppose.

Is there anything special about the message? Is it large, does it have a lot of recieved by: headers? Attachments of any special type?
