Email headers - To: vs Envelope-to: - which takes precedence and why
The scenario:

A customer has received an email that she believes should have gone to the general manager. I have a copy of the internet headers, which include:-

Envelope-to: gm@domain.co.uk
To: <bookings>

Although there is a bookings@domain.co.uk, you can see from the above that the To: field doesn't contain a full email address.

The email WAS intended for gm@domain.co.uk so why did it end up in the bookings@domain.co.uk mailbox?

The email server runs SBS 2003 (Exchange 2003 with Microsoft POP3 Connector).

There are no errors or warnings for this email in the event logs, and if I track the message in Exchange System Manager, I can see that it was forwarded to bookings@domain.co.uk

I "assumed" it should have gone to gm@domain.co.uk because that was the address assigned to the Envelope-to: field.

I have installed a POPCon as an alternative to the outdated MS POP3 Connector - hopefully this will resolve the issue.

I'm on holiday from today until the 22nd October, so will not be able to follow this up until my return.

I agree SMTP would be better, but in this instance, becuase of the geographical location, the customer still uses dial-up.

Then they should add an intermediate mailstore.  One that is available 24/7 and retrieve/send when the machine is connected?

If they are using dial-up do they have a dedicated line and is their modem setup to reconnect if line dropped? Is DSL or satellite not an option?

DSL may be an option at some point in time but not yet. Satellite is too expensive for their needs.

ALL of their email goes to a catchall account with their web host, and then their POP3 connector downloads the email and forwards it to Exchange.

I've tried POPCon as a 3rd party alternative, but apparently it's still happening....
