emilio:~ # grep submission /etc/services submission 587/tcp # Submission submission 587/udp # Submission
It permits users send or receive mail. Admin tasks are made through ssh and some logs are sent via syslog.
Why is sendmail opening "submission" port??? What is it intended for? Is it insecure??? Could I close it? How?
A port as such is never "insecure" (please don't prove me wrong...).
sendmail uses port 587 by pure coincidence. Next time it will be another
port.
