php mail() prints mysterious error

Question

I'm trying to use the mail function in PHP, and it simply yeilds this mysterious error in the error log:

sh: 1: -t: not found

I have both sendmail and mailutils installed, as well as set the sendmail path in php.ini.

I've looked at this, and I tried the suggested fixes there with no change.

What could be causing this issue?

Answer 1

What is the sendmail_path set to in php.ini? It should look something like this if you are on a Unix system.

sendmail_path = /usr/sbin/sendmail -t -i

It sounds like the "/usr/sbin/sendmail" piece is missing.
