mail() problems

[Anon]

I am experiencing problems with the mail function.
All I want to do is print a url with an appended query string at the bottom of the message. Unfortunately, for some reasons I don't know, something really strange happens:

given a URL of the type http://www.whereever.com/blah.php?a=a&b=b
the URL printed in the mail is:

.../blah.php?a=a&b=b

In other words, in my final URL I have both the decoded and encoded & sign (&amp😉 with the result is that the variables contained in the query string will not be available to the blah.php script.

Any ideas? By the way, I never urlencode anything anywhere in the script generating the email.

Thanks,

S.

The message I've just posted is sligthly confusing because both encoded and decoded strings for & came out the same on the html page. sorry about that

P.S.: it makes more sense if you view the source code of the message...
