SMTP Error message undeliverable email
I am receiving the below bounce back when sending an email from 1 email account on my domain; helpdesk@octree.co.uk, this only happens when sending to a handful of domains but it is a big problem as this is the email address we use for our support helpdesk.
Any help is greatly appreciated.

Does that mean anyone other than helpdesk@octree.co.uk can send email to that domain?

Yes
can u compare a working and the helpdesk account using LDP.exe and check which attribute is missing.
If both are using same account type.

Could you please explain the above process.
any resolution to your question. we're having the same problem but seems to be a problem with the receiving end flagging us as spam i think.
