Something had to have changed on the server for it to just stop working one day. Have you tried restarting sendmail? Did someone enable selinux or something else that would block sendmail's execution?

Question
webmail clients not sending email under Plesk 8.2.1/ RHEL3
Hi, everything was working ok on my linux web hosting server, until today.
Squirrelmail 1.4.2 is giving the following message after user clicks "send":
"Warning: popen,curl_exec,curl_multi
been disabled for security reasons in /usr/share/squirrelmail/cl
I also tried IMP/Horde, which gives me the following error:
"There was an error sending your message: Failed to open sendmail [/var/qmail/bin/sendmail] for execution."
Outlook still works over IMAP/SMTP
Any ideas?

/usr/share/psa-horde/confi
$conf['mailer']['params'][
$conf['mailer']['type'] = 'smtp';
So now Horde works, but squirrelmail still gives the same error.
