use /usr/sbin/sendmail in php exec()

[endelwar]

when I use /usr/sbin/sendmail directly in a php exec() this error is reported: "sendmail cannot be called directly from a shell with the current user id".

I've already tried /scripts/eximup --force that changed permissions from -rwsr-sr-t to -rwxr-sr-x but didn't worked; I've also upgraded from 4.52 to 4.62 (downloaded from diff.cpanel.net) but no results again.

Firstly, why do you want to use exec() to send mail via sendmail - can't the mail() function be used?

Secondly, check that you don't have the SMTP tweak enabled in WHM > Tweak Security

Well, Mailwatch asks for it, so I must follow his rules

Secondly, check that you don't have the SMTP tweak enabled in WHM > Tweak Security

I've disabled the SMTP tweak, but it doesn't work. It reports the same error.

Try checking the permission of the /usr/sbin/sendmail binary .

Try checking the permission of the /usr/sbin/sendmail binary .

now they are set in this way:

-rwxr-sr-x    1 root     mailtrap     8599 Aug 16  2005 sendmail*

How should I set them?
