Where is the code for sending mails

[chrisvn]

I am troubleshooting with my web hosting company and they are asking me:

Please tell me your source code use send email at page http://www.web-ranking.vn/how-to-do-key ... earch.html to we check source send mail from your website.

Which file is the file that contains the code for sending the double opt in emails?

It is the sendmessage() inside lm_functions.php
It uses the standard PHP mail() command.
