[postfix-users] mail from root rejected

[rh]

I have dovecot mailserver running well. Everything is fine except that
mails from root are rejected (some system processes are sending messages
by mail using root as sender). In the logfile i get:


Feb 25 10:05:51 Beethoven postfix/qmgr[5228]: 0C7A8652489: from=<root at mydomain>, size=893, nrcpt=1 (queue active)
Feb 25 10:05:51 Beethoven postfix/smtp[5662]: 0C7A8652489: to=<hnat at mydomain>, relay=smtp.inode.at[62.99.194.14]:25, delay=0.08, delays=0.04/0/0.02/0.01, dsn=5.0.0, status=bounced (host smtp.inode.at[62.99.194.14] said: 550-Verification failed for <root at mydomain> 550-Unrouteable address 550 Sender verify failed (in reply to MAIL FROM command))


What can i do to have these mails forwarded?
