Mailserver Problem

[trysb]

Hello,

We have a PHP forum setup much like this one but we keep getting this error on monay e-mails it tries to send out.

This message was created automatically by mail delivery software.

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:

anything@hotmail.com
unrouteable mail domain "hotmail.com"

Does anyone know how to fix this?

Thanks
Brian

Is this on a Windows box running MailEnable? I would assume that this is on an Ensim box (Linux) but thought I'd ask because I had the same error message on a W2K3 box w/ mailenable. If this is a Linux box with Ensim, do you have recursive DNS allowed for local lookups?

It is a Lynx system and i dont know if it is running MailEnable how do i find out?

Check your "php.ini" file. Make sure that the "sendmail_from =" line under "Module Settings" reflects an e-mail address that actually exists on the local server. I was having a similiar issue with vBulletin until I changed that line.

I assume you mean Linux - so, no you do not have MailEnable. Sorry I can't be of more help.

I'm a new to SB, and I have the same issue:

All mail intended for hotmail, yahoo, or aol is being rejected. All other vanity domain names, etc is working fine. I'm assuming that this is all a result of a blacklist on SB IP space.

I've found the source of the problem. My IP was not blacklisted, however it was being denied by Aol, Hotmail, MSN, ets..

When I changed my mail preferences on the server via WHM, it resolved the issue.

Apparently the ISP's were denying my mail as I think they suspected my 'nobody' address as an open relay. When I changed my server default addresses to know / real account, mail began flowing properly.

(I have a linux server with cpanel)

in WHM, on the left nav, it's under the first section: 'Server Setup'

Click on the 'change system mail preferences' link.

Change the 'nobodys' and 'root' mail to a known value.

it worked for me.
