I know Comcast blocks port 25 so this is  confusing. Usually  this user  connects Via the company vpn and emails from his computer which is set to smtp port 587

If he emails by way of the Vpn-he connects to his own server which should be port smtp 587- why does it say: Attempting SMTP connection to [Parks.org.uk:25 ?

If I'm understanding your question correctly - you have a user who used to VPN into a network to connect a mail client to the server on port 587 and now the person has moved to England and is attempting to do the same thing, but it appears that the email is using port 25 and the wrong server.  

My guess, based on the evidence, is that the email client is not correctly configured to point at the server on your network.   Its actually configured to point at parks.org.uk:25.  The user might have a second account configured to use that configuration

He is just visiting on business and when he left
Everything worked fine from the US, now he is in a hotel
Connected to the server in the us by VPN but he gets the parks.org.uk :25
If he is connected to the us server by VPN why does MDaemon say that?

What I'm saying is that either 1. he is not on the VPN and thinks he is - can he get to an internal website with his browser? or 2 he is connected to the VPN but his mail client is trying to connect to parks.org.uk:25 because it is configured to do so. - you might try setting up a webex meeting with him and trouble shoot that way.

Basically what I'm saying is that if logs say that he is trying to connect to parks.org.uk then that is what the client is configured to do and something got reconfigured from when he left the US and tried to connect from the UK.

Is there some kind of automatic configuration script that could be running?

No there wasn't any auto script running. So far it has not happened again.
