Hi, I've been using CPanel as a member on a shared host without the slightest problem up until about two months ago, and now I'm having major email trouble. Our server was upgraded to PHP5 right about the same time I had formatted my drive, and somewhere in that commotion I ran into problems trying to get Outlook re-installed and connect to my outbound smtp server. It failed connecting to "mail.mydomain.com", although the Auto-confgure reg keys listed it as both in and outbound. I went through several articles on this board trying to resolve the problem which led to me trying various configurations of SpamAssassin, BoxTrapper, and Spam Box, and then somewhere along the line it showed a test email's path was actually using our shared-host provider's outbound smtp server. Setting Outlook to use that server instead and then checking "requires authentication" got my email up and running again through Outlook. However, I am still unable to send mail outside of my domain using PHP. I can send to email@example.com fine, and PHP will claim messages are sent to others OK, but it never reaches me@anyotherdomain. I've read about examining exim.conf for clues but am unable to find it on my server. I know that I have an insecure contact form on the site that needs dealing with, is it possible that a spammer has used it to somehow hi-jack my outbound smtp server completely? I know that this is the type of thing that I should be bothering my host with, but to make a long story short,..that's much harder than it sounds. I don't have direct access to php.ini or WHM, but am able to access my entire domain using FTP and CPanel. I'm just wondering if there are any local settings that I might have missed or toggled in Cpanel which could trigger this to happen, or if the issue could possibly be resolved by using php's ini_set to override global email settings. If it helps,..phpinfo says: sendmail_from no value no value sendmail_path /usr/sbin/sendmail -t -i /usr/sbin/sendmail -t -i SMTP localhost localhost smtp_port 25 25 ..and I now have all CPanel Spam-fighters disabled for testing. Thanks a lot for any assistance on the matter. P.S. Is WHM typically installed alongside Cpanel for member access on a shared host or is it more a toy reserved for admins? I'm jealous, it sounds like an excellent program. BTW, I also checked to make sure that neither my domain or the host's has been blacklisted.
