Links does not work in <a href> tag when content has .com inside

in my code I generate a body of a html email message. Part of it is following:

<a href="mylink.pl">SomeName.com</a>

When I receive this email in my Mail client or in Gmail and when I click the link I'm directed to the SomeName.com and not to the mylink.pl which is in the href part of the <a> tag. And it looks that this situation occurs only for the .com domains.

Any ideas how I could deal with this?

Use absolute URIs in emails. They start with (usually) http://

What you have is a relative URI, which doesn't make much sense in an email. You are probably just hitting your browser's search function when you try to visit it.
