One of my users has raised a request to look into an issue they are coming into, and I am stumped.
They have written a piece of code in C# to send an email out, using these settings:
"port": 25,
"deliveryMethod": "Network",
"useDefaultCredentials": true,
"host": "localhost"
Within the email, there is a URL link to a page on confluence, which is perfectly normal, and when the program is run from his local machine, this works properly, however, when sending through one of our servers (Windows Server 2012, R2) , the URL gets transformed, into something like below:

(link changed slightly)
The original URL was
https://codehouse.atlassian.net/wiki/spaces/APM/pages/1354236014/2019-04-15+Azure+Elevated+Access+Prolongation
I for the life of me cannot fathom why, any ideas?
1And how the original URL looked like? – montonero – 2019-04-18T13:31:47.330

It looks like a some corporate URL filter to me. It replace all URLs in emails and redirect them to a corporate server which checks if the link is harmful and pass them through if not. – montonero – 2019-04-18T15:09:55.370
