Error 554 5.0.0 MX list for mycompany.com. points back to ns.mycompany.com

[Oleg Prokopyev]

does your mail-server know that it must receive mail for your domain?
for example if you have sendmail then in file /etc/mail/local-host-names
or /etc/mail/sendmail.cw (depends on sendmail)
you should have a record "mycompany.com"
