I have setup lansuite 2003 but unable to send any emails from clients. incoming are ok.
The error is: -
12:55:48 PM SMTP: [3] SMTP connection to 'mail.btconnect.com' established.
12:55:48 PM SMTP: [3] 550 Recipient Not Authorised [recipient rejected due to no authorised destination groups]
I have a domain with forwarding setup to a btconnect account and I am dialling BT as I am using a BT connect ISDN line so have to use their number.
The client is setup for the email and reply address as user@domain.co.uk
Any help very much appreciated.

This looks like the mail is being rejected because you are blacklisted or need to be added to a white list. Contact btconnect for help.

I am also with BTconnect and had the same problem.
The method BT prefer is to transfer your domain to them ;-}
I also registered for their domain recognition list but could not get it to work for me.
There are several ways I have tried to get round this.
The easiest but inelegant method is to use the BTusername as your from address. i.e. BTusername@btconnect.com for all your users. You will then have to rely on the return address in each client(we use outlook) each outlook will have their own return address of user@domain.com
The problem we had with this was some mail readers did not read the return address and would use the real address when replying.(Mostly Mac customers!)
Next I tried bypassing BT and used the LS2003 SMTP to send directly. This was the best method, fastest and most controllable.
The problem was some Mail servers do not accept mail from unknown smtp addresses. Particularly AOL.
What I have finally settled on is to use the mail service provided by the host of our domain. (If you try this method, don't forget to stop the redirection to BT)
