e-mail from my server is blocked

[harveyc]

I haven't had this problem e-mailing to users at this ISP before, so p-z must have just recently been blocked. How do I got about getting this corrected?

Here's the error message:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

user@frontier.net
SMTP error from remote mailer after MAIL FROM:<me@mydomain.com> SIZE=2364:
host mx.frontiernet.net [66.133.128.228]: 553 sorry, your mailserver (216.180.241.1xx) is rejected. Reverse DNS queries for your mail server IP fail. See http://postmaster.frontiernet.net.


Also, I don't know if this is related, but I also have Spam Asassin blocking e-mails I've forwarded back to myself. Looking at the IP, I'm guessing it's my ISP that's blocked. Right? I get the following message:

Hmm... for starters these are two seperate issues, assuming you use the PZ outgoing mail server instead of your ISP's outgoing mail server.

I assume from the partial IP you've posted that you're on server number 8? If that's the case I don't know why your mail was rejected. The mail would suggest that your mailserver does not have a "reverse DNS" entry set up, but it certainly does - you can check for yourself at: http://www.dnsstuff.com.

Try plugging your _domain_ into the mail test at http://www.dnsreport.com/ and see if it flags anything. It's possible (but not likely) that one of the domain tables on the server might be corrupted.

Have you been getting this message repeatedly or just once?


As to the SpamAssasin question, your ISP's IP has indeed been listed in the Sorbs blacklist as either protecting (or not adequitely safeguarding against abuse by) spammers.

You can get more info by putting your ISP's IP into the search feature at http://dnsbl.sorbs.net

This has nothing to do with PZ, and would need to be discussed between your ISP and the people who maintain the Sorbs listings.
