I've searched through the forums looking for the answer to this, but haven't quite found it. Mail is working normally on my system, send/receive no problems. Telnet to port 25 or 110 is less than a second. I have -Rt0 in /etc/xinetd.d/smtp_psa The problem is when sending mail through PHP. It works correctly, but it's slow to make the connection. Like 2 minutes or more for the form to come back. I have the following in php.ini sendmail_path = /usr/sbin/sendmail -t -i I've also tried sendmail_path = /var/qmail/bin/qmail-inject -t -i but while that allowed the form to come back quickly, I never received any mail. What is the proper sendmail_path for PHP when using Plesk (I'm on 7.5.3) or how can I speed this up? I don't want the user waiting 2 minutes or more for the form to return. Thanks for any advice.
