php - mail() and sendmails clientmqueue directory

I'm setting up a contact page on a site. Typically I use form inputs to assemble the data and then use the mail() function to send the data to the appropriate user. Whenever I submit the form data, I immediately see a system error reporting that sendmail (version 8.12.1) cant chdir to /var/spool/clientmqueue ... and naturally the mail does not get delivered. Permissions and ownership of this directory are 4770 and root.smmsp respectively. (smmsp is the SendMail Mail Submission Protocol userid/groupid). If I change permissions to 4777, the mail gets through, but I get a syslog warning that I have dangerous permissions set for that directory (I agree). Has anyone else experienced this issue, and or can anyone recommend a secure solution. -- Regards Luke ------ Q: What does FAQ stand for?
