Nagios + Postfix

[Martyn]

Proweb is not under my control

I'm not to sure what you mean with regards to the rest of you reply, I have
not set up postfix to masquerade anything, would not know how to do that

I'm sending the mail from the Nagios Server from address
nagios at cna.localhost to notify at proweb.co.uk

I have not configured postfix in anyway, the install guide just implied that
I did the following and it would work out of the box so to speak

apt-get install sysutils mailx lsb-release postfix

Do I need to carry out additional steps in postfix, if so what are they.

Thanks for your reply

Sounds like mail.proweb.co.uk is rejecting your connection. Is that a server
you control? What do it's logs say about the transaction?

If it's not a server you control, are you following standard/expected SMTP
conventions? Is the e-mail address being used as the from valid (i.e. is the
@domain part legitimate and exist in DNS)? This often comes from the
hostname of the machine if you've not configured postfix to masquerade that.
Does the public IP for your sending machine have valid reverse DNS, not on
an RBL, not on a known 'dynamic' IP? Are you permitted to use that server to
send mail?
