we are planning on moving a web site from one hosting company to another, both services being dedicated linux servers, but the new company's host is not accepting "-r" argument of sendmail.
one of our developers is normally using sendmail with -r option, which overrides the default Return-path an the following works on the old dedicated server
/usr/lib/sendmail –t –r web@[domain].com
how can we specify different return path when sending e-mails. there are two domains on our host and depending on the domain name we want the returns to be handed to web@ the respective domain.
on the new host however we get this
sendmail: illegal option -- r
sendmail: usage: sendmail [ -t ] [ -fsender ] [ -Fname ] [ -bp ] [ -bs ] [ arg ... ]
there are also various qmail processes running, which we did not have on the old server.
