Question

How to turn off SRS (Sender Rewriting Scheme) support in Plesk Onyx ?

Answer

Connect to the server via SSH.

Open /etc/postfix/master.cf file in a text editor and find the next string:

plesk_virtual unix - n n - - pipe flags=DORhu user=popuser:popuser argv=/usr/lib64/plesk-9.0/postfix-local -f ${sender} -d ${recipient} -p /var/qmail/mailnames

Add to the end of the string “-s” so that the line is:

plesk_virtual unix - n n - - pipe flags=DORhu user=popuser:popuser argv=/usr/lib64/plesk-9.0/postfix-local -f ${sender} -d ${recipient} -p /var/qmail/mailnames -s
