Hi,

the company i work for are due to migrate our email services to the new BT office 365.

i understand that i can use stunnel or igetmail to sort out the collecting email from POP mailboxes , which is fine..

but how do i configure SMTP to send email? i see that i can set TLS on the connector, but how does it authentcate?,

do i just use the admin account username and password ?, as i cannot see how i can setup and individual one per user.

as everything i have read tells me i need the username and password for the email address im sending from.

the local account usernames and passwords are different to the email settings at BT's end.

or do i just need to enable TLS or use stunnel to encrpyt SMTP with the same settings i have now.

the server is an SBS2003R2, which is working fine at the moment but BT have given me a deadline date for the move..

Thanks

bob

Hi Bob,

You can continue to use BT's mail servers for outgoing mail. If you want to use Microsoft's servers then the information you need is on this page.

[Update below]

I've been told that using BT's servers post-migration is hit-and-miss, it may work but it's possible that it will stop after a while. You would be best to use the MS servers.

I'm not sure exactly how complex your on-premises setup is, but here is an MS Knowledge Base article on setting up IIS to use Exchange Online as a SMTP relay. The concept would be similar for other MTAs as long as they support TLS/SSL connections. I think that the section on supporting multiple email addresses using proxy addresses would be of interest since your on-premises user ID's are different to the email addresses that you want to send from.
