Duplicate email problem using php mail()

[kroleig1]

Hi all

I am having a problem with duplicate emails being sent on registration. I am using a very simple php mail() function to send the registered user an email confirmation link.

Problem is, is that it sends the user 2 duplicate emails, and after a while the registration script doesn't even send any email confirmation anymore. Does this duplication cause me to be banned?

How do I fix this problem...

I tested it with many different email accounts public and private and the same problem occurs.

Thanks in advance for your help
