Compare both files called ../blogs/conf/_basic_conf.php.
The email is set in line 96:

/**
 * Your email. Will be used in severe error messages so that users can contact you.
 * You will also receive notifications for new user registrations there.
 */
$admin_email = 'postmaster@localhost';

In ../blogs/conf/_advanced.php you can set the mail url in line 146:

/**
 * Default email address for sending notifications (comments, trackbacks,
 * user registrations...).
 *
 * Set a custom address like this:
 * <code>$notify_from = 'b2evolution@your_server.com';</code>
 *
 * Alternatively you can use this automated address generation (which removes "www." from
 * the beginning of $basehost):
 * <code>$notify_from = $instance_name.'@'.preg_replace( '/^www\./i', '', $basehost );</code>
 *
 * @global string Default: $instance_name.'@'.$basehost;
 */
$notify_from = $instance_name.'@'.preg_replace( '/^www\./i', '', $basehost );

mail could be received at b2evo@YOURDOMAIN.???

Afwas,

Thanks alot for the tip.

I will look into it asap, and report back here.

Okey, now checked everything, and all seems okey, but still it does not work ;-(

But strange, this is what I have noticed.

I am in a test period, building the blog system.

I have 9 blogs, numbered: 1,2,3,5,6,7,8,9,10

Blog # 4, was the linkblog, that one I have deleted.

Email notification works on my posts in blog 1,2,3 and 5, but NOT in blog 6,7,8,9 and 10 ????

I have made serveral "scans" on the blog settings, and they are all the same.

Must admit, that after installation, I made a new admin account, and deleted the original. Could this by any change have made an impact to the system ?

I have tried deleting all of the test post, and then remade them again, but this don't change anything, notificatio works in blog 1,2,3 and 5, but not in 6,7,8,9 and 10 ;-(

As always, any help is highly apriciated.

I now think that this might be a bug, and therefore, I have posted this information in the bug for 1.9.3 forum here: http://forums.b2evolution.net/viewtopic.php?t=11316
