Hello,

I am using hostmonster to host my XOOPS 2.3.3 site. I want my users to register on my site, get registration activation code delivered to their specified gmail/hotmail/yahoomail etc account, and confirm the registration.

I found that I need to change the default php mail() to sendmail to get the "activation code delivered" message shown after the user registration. Note except for this parameter, I have not changed other default settings. And the "From address" is set as "webmaster@mysite.com". But the user does not get the "activation code" mail in his gmail/hotmail etc. I wonder if I have missed anything in the configuration? Many thank.

Are other emails or destinations working?
If not try the SMTP settings. Refer to the mail settings of your webmail for the parameters.

I forgot to set the "admin mail address" in general setting to the correct email address.
