relay access denied error 554

[GazzaS]

Hi,

A company I manage the IT resources for has recently had a Notel phone
system installed. Part of this phone system included installing a third
party software system into Outlook that manages the voicemail
(CallPilot Server).

Since they installed this software the users are unable to send emails
(they can receive) and the user is greeted with a "CallPilot Server:
Your Mailbox has been disabled" error when outlook starts.

My first thought was to uninstall the Nortel software which did stop
the error. However when a user still tries to send an email they get a
"550 relay access denied" and "554 relay access denied" system error
return email.

I've enabled SMTP authentication and checked and double checked the
settings against my PC that works fine (no Nortel).

I'm thinking that the Nortel software has changed a setting somewhere
that has stopped the SMTP authentication.

Any suggestions would be most welcome.

Kind regards,
Gary

You might want to try here www.tek-tips.com. You need to register to
access the forums but it's free. They have a section specifically for
Nortel systems.

My guess is that your emails are being routed through the Nortel system
and your SMTP server thinks they are being relayed. This is a tactic used
by spammers. Most ISP now will not accept mail that's been relayed.
I'm not really sure how it all works but I think the ISP's require a
reverse DNS. Maybe someone else here can elaborate.

Hi,

Thanks for the info. I suspect you are spot on with the routing aspect.
Now I just need to work out how to stop it.

Kind regards,
