Internally mail sent to comp...@company.co.uk main SBS distribution group goes to the users which are members of the group, usual behaviour.
Administrator is not a member of this dist group currently so doesn't get a copy...
If I send a message from externally then the message *only* goes to the Administrator mailbox and behaves/reports as if it were sent to the Postmaster ???? and no-one else gets it at all ????
Mail is MS POP3 collector
Doesn't affect other accounts in this way, only the main dist group..any ideas ?

Assuming since you have the POP3 connector in place, and there is only one MX record for your domain that points to the hosting provider, and all mail going to your company from the outside world are going to the provider, then at your POP3 hosting provider, has this group been created?
Also, in the distribution group properties, is it allowed to receive mail from Everyone?

If I send a message externally to postmas...@company.co.uk
It is delivered into the Administrator inbox and says that it was sent To the 'Administrator' this is correct as postmaster@is an alias for the Administrator account.
However the external messages sent to comp...@company.co.uk ( which should be directed to the members of that group internally) appear to go into the Administrator's Inbox but say that they were sent To 'postmaster' ...why do they say this as opposed to 'Administrator' as with the messages sent to postmaster@

No, not necessarily weird. I made a few assumptions in my last post. Can you confirm or respond to them, please? Allow me to re-clarify my questions for your convenience.
1. What is your MX record pointed to? Is the MX record pointed to only your POP3 provider, or to both your POP3 provider and to your server?
2. Does the Distribution Group properties allow for Anyone (Everyone) to email to it? Look in the Dist Group properties in ADUC.
3. Has this group email address been created at your hosting provider?

1. Two MX records both pointing to the same IP address which is 1and1 server in Germany by the looks of things..
2. Yes it does, as I've said earlier it works fine internally.
If I mail the group internally then all the users who are members get the messages, the Administrator account isn't and doesn't, expected behavior.
If I mail the group externally then the message *only* ends up in the Administrator's Inbox and says that it was sent to 'postmaster' in the To column ? Why does it say 'postmaster' why hasn't this changed to 'Administrator' the owner of the alias ?
If I mail postmas...@company.co.uk externally then this ends up in the Administrator's Inbox as you'd expect and says that it was sent to 'Administrator' in the To column ..as you'd expect totally normal.
The company get a lot of messages from their website which are sent to comp...@company.co.uk and of course these are ending up in the Administrator's Inbox and report that they were sent To 'postmaster'
This is why I have been asked to investigate.
They want the messages to be distributed to people in the comp...@company.co.uk members list.
3. The hosting provider has *...@company.co.uk forwarded to a catchall POP3 box called comp...@company.co.uk ...could this be the problem ? Perhaps we should change this so that it perhaps forwards to a catchall called something else ? catch...@company.co.uk maybe ?
Previous web designers have set this up at 1and1 originally.

I opened up port 25 temporarily and sent a message from telnet session to comp...@company.co.uk and it was routed correctly just to the members of the dist group.
This seems to indicate that it should be something to do with the catchall POP3 I would image ?

Yes. A POP3 server really expects mail for just one user per mailbox, so doesn't bother keeping the SMTP recipient address, which does not necessarily appear in any header (it may be in some Received: headers).
Domain-wide POP3 collection relies on the To: header to route the mail.
BCC emails, and a mailing list email is just a big BCC, deliberately do not include recipient information in any header, only in the SMTP address.
QED.
In order of preference:
-Use SMTP to receive mail.
-Use individual POP3 mailboxes. More trouble to administer but sorts out this problem and eliminates a lot of spam. Obviously the POP3 connector must also be set to download mail individually.
-Check that the POP3 server adds a header containing the original SMTP information: typically Envelope-To:. The SBS POP3 connector cannot use such a header but most third-party downloaders can.

You need to review the POP3 Connector settings, because those are what control this.

I think you answered your own question. I would remove that * catch all address. And having two MX records to one IP is superfluous.
The postmaster response is a standard responder based on mail RFCs to respond to a sending MTA with error messages, such as what you are seeing. That's why it doesn't show up in the administrator's mailbox.
