Email with lots of links fails

Question

I am trying to send an email using an Indy Email Client. The body of the email is pretty much a list of various websites (like 50 to 100). The email server is Yahoo. I am finding the email is not going through (I get a "Connection Closed Gracefully" exception). But if I change all instances of "/" to different letters the email goes through. Example:

Change http://mysite.com/mypage.html to http:XXmysite.comXmypage.html

Could the email server be rejecting the email because it looks like spam?

Answer 1

Turns out Goadddy was denying them because links contained in the email were noted as spam sites.
