Hello

I don't know the source of the behaviour, but I have a guess.

we've just transferred our forum to a new server (and a new hosting company). Everything works fine. But the notification emails have now 3 email adresses in the header. Let's assume the name of the forum is "My great Forum" and the domain is "forumdomain". I find the following in the email:

xxxx@12345.hostserver.com
yyyy@12345.hostserver.com
my great forum <notification@forumdomain>

Where do the both emails with the hostserver adresses come from?

I assume, it comes from the email server of your new hoster.

Can I change anywhere the sender name of the notification email?

If I'm right, ask the hosting company (FAQ, technical customer service) for the sendmail or mailserver parameter, that you need to send mails via the PHP-function mail(). In many cases it is something like -f emailaddress@example.com. Put the parameter into the enhanced settings, field named mail_parameter.

Then it should work (in case my assumption is correct).

Tschö, Auge
