MyBB Community Forums

My users cant receive any email sent from forum, like registration confirmation, email on PM and all type of emails..
These emails are returning to my email with error which is..::

Quote: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:

[email protected]
SMTP error from remote mail server after initial connection:
host i.mx.mail.yahoo.com [74.6.140.64]: 553 Mail from 178.239.49.35 not allowed - 5.7.1 [BL22] Connections not accepted from IP addresses on Spamhaus SBL; see http://postmaster.yahoo.com/errors/550-bl22.html [550]

Plz guide me, this is very big problem for a forum..!!

By the looks of things yahoo have blacklisted your host IP. It may not be your fault, as it may be someone else on your server.

You will need a new IP, which is generally only solved by moving hosts

According to the error message returned by yahoo, you are listed on the spamhaus sbl list. Visit their site to find out why and how to get removed.

Edit: actually if you follow the link in the return message it explains it all

Then what should i do?? except changing host???

The answers are all on the Spamhaus website.

This is nothing to do with MyBB.
