I receive mails.. a lot of mails...

Mail = info@busimatch.com

Subject= Cron <busimatch@server11347> /usr/local/bin/php -q /home/busimatch/domains/busimatch.com/public_html/periodic/cron.php

In the mail: Wrong password.

What can i do to stop it?

Do you have the SMTP mailer module installed and enabled? If so, double check settings. Primarily the password which is what the message says is wrong.

Also. Are your aware that 99.9% of sites don't even need the SMTP mailer module. If you have it installed, make sure you actually really need it. If your site can send email to members without that module installed, then you do not need it.

 I have a funny feeling after reading his post about the profiler that he has EVERY module installed.

I've always wanted to ask this question. What is the profiler?

Debugging module. Shows how much memory a page uses, how many SQL queries fired, etc. You know, debugging stuff. Nothing to do with profiles. And it bugs me whenever I check I site and see it installed (and when they install it, they completely ignore that they need to also make a quick file edit for it to actually start running).
