Sendmail: "550 Relaying denied" after boot up; restart sendmail solves problem !?!

[Rob]

Hi,

I have a weird problem with my mail server.
It's running 6-Stable as Feb. 23rd.

After a boot up, sendmail refuses to deliver
emails with a

 reject=550 5.7.1 [...] Relaying denied

When I then simply restart sendmail manually:

  /etc/rc.d/sendmail restart

the problem is solved and email is correctly
delivered without any Relay denials.


Any idea what this can be?
And how to get this right immediately after
boot up?

Thanks,
Rob.
