Autoresponder Problem in ver 110.0.5

Hey, for a long time in the company where I work, after setting up the autoresponder, a message appears on some e-mails of recipients ----------------------- This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: pipe to |/usr/local/cpanel/bin/autorespond b@a.pl /home/m/.autorespond generated by b@a.pl (ultimately generated from r@a.pl) The following text was generated during the delivery attempt: ------ pipe to |/usr/local/cpanel/bin/autorespond b@a.pl /home/m/.autorespond generated by b@a.pl (ultimately generated from r@a.pl) ------ The argument contains empty host portion of address at /usr/local/cpanel/Cpanel/Email/Object.pm line 164. ----------------------- maybe someone had a similar case and knows how to solve it
