Email notifications not working properly

[Shoonra]

All of a sudden my inbox is flooded with error messages about email notifications not going through.

The errors show the domain name of my site to be wrong. Here are some examples of error messages -

I haven't done anything to the forums - no upgrade no nothing. I am hosted on a dedicated server and to the best of my knowledge no one has bannned our ip (we NEVER spam) - also the addresses that bounce are varied (not AOL or netscape so far as far as I see).

What's going on?

The problem is probably your return email address:

[email protected]

Did you change this anywhere?

Nope - I didn't change anything. Plus it is still working in some of the cases...

[Steve Machol]

Well that is the problem. Some outside domains are rejecting that return address because they cannot find the 'thecatsite.thecatsite.com' domain. I suspect you need to fix this so it's a standard address:

[email protected]

As I haven't changed anything I don't know where to get anything fixed In the admin panel all I can see is webmater's email and that is just fine.

What is the webmaster's email address? Also upload the phpinfo.php file from the 'extras' directory of the zip file to your forums directory. Then post the URL here.

Webmaster's email is set to - [email protected]

here's the link to the phpinfo -

Thanks for all your help!

I had another problem with return-path in emails and fixed it for me.
Maybe you can do the same, look in this thread:

Thanks zfrank! Unless I am told I absolutely have I'd rather not play around with the code. I'm PHP shy

[Shoonra]

Steve, have you had a chance to look at that phpinfo file? I don't want to leave it there for too long as I was told it might help hackers in some way.

BTW I just upgraded to version 2.3.2

[Steve Machol]

Sorry, I missed that. There's nothing in the phpinfo that would account for this problem.

And what is this:

System Linux thecatsite.thecatsite.com 2.2.23-rp1 #3 SMP Tue Dec 10 13:55:27 CST 2002 i686

Hostname of this server is thecatsite.thecatsite.com

sendmail_from is [email protected]

I think on this server is qmail running and in /var/qmail/control/me is thecatsite.thecatsite.com, normally it must be thecatsite.com

[Steve Machol]

Sheesh! I totally missed that. Good catch!

[Shoonra]

Thanks for catching that up - I just don't understand why it's changed all of the sudden. I guess I should contact my hosting service next.
