I have got the firewall rules permitted from our RHEL 5.x & RHEL 6.x servers to our SMTP relay server (it runs on RHEL 5.8).
In the past, I recall I have a server that I could just issue mutt command below & it will send email out via the relay server at that site: mutt -s "Test mail" -a /tmp/file.tar.gz ab...@nixdorf.de < /tmp/mailmessage.txt Now all servers (at another site) can't send email out. Did I need to set something at this site's servers or is there any way that I could specify the SMTP relay server in the mutt command? In Windows, blat & sendemail allows me to specify the SMTP relay server. TIA
