There's a couple diferent threads going that all relate to this so I'm just posting it once under this thread. I too experienced a problem with sending mail after upgrading to v5.2. I have discovered that the symbolic link 'sendmail' has been deleted on all of my servers that have 5.2 installed. This would have an impact on Webmail, PHP, Perl, etc. Here's how to check/fix the problem:
1) Check you /usr/sbin directory for a link file called 'sendmail'.
2) If it is missing, execute this command in the /usr/sbin directory:
ln -s exim sendmail
That should fix your problems.
