Thanks for adding a comment Sandy.

If you don't know what kind of restriction have been placed on the mailserver of your provider it is normally the easiest way to simply ask the provider what restrictions have been set.
Of course, the person you are getting on the other end of the line might not be much wiser than you (happened to me).
And me, especially since most of the call centre folk are Windows junkies ie asking me what I use to scan for viruses on Linux and my favourite 'Go to Start.....'. I sometimes just for fun say I casn't see it and my 'Start' button has disappeared :)) Wicked I know but the staf need to know Windows is not the only OS they are having connect to their network.

I have phoned them on 5 different occassions to get two totally different answers to the same question about which SMTP server to use. When this happens I know I am smarter and decide to try and figure it out myself.

The other method is to simply test it. Usually, when you try to send an email and the mailserver is refusing to accept the mail you get a reject code and error message. Normally this is enough to understand why the server refused the message.
Well after some testing, the reason the mail is not getting through is because the ISP do authentication to confirm the email sender is the same as the person dialed into their network.

Postfix can of course use authentication when sending mails to the relayserver. It depends on the receiving relayhost if it is configured to only allow the sender address that you used to authenticate with to the relayserver. Most relayservers are configured to require authentication when you want the relayserver to accept a message and have it relayed to the internet. Again, the error message should appear either when sending in mozilla or in the log of your local mailserver when you try to send a mail to the relayserver.
That's just it, there was no error message but the messages I sent didn't get through and in some cases two copies were placed in my sent items.

I have decided to change ISP's but due to financial constraints can only do so in September/October.
