[TYPO3] Direct Mail Fetching Problem

[Samuel Stephens]

Hi, All
I didn't see that this problem has been addressed yet, so forgive me if 
I'm repeating an old question.

Whenever I try to use the Direct Mail Extension, I get the following 
error when I create a new direct mail:

"An error was encountered.

The plain text content could not be fetched.
The HTML content could not be fetched."

I've tried clearing the cache, double checking the configuration, 
changing the configuration, etc. Nothing seems to work. Does anyone else 
have this problem and know what causes it and how to fix it?

Another note: One time the problem fixed itself overnight, then came 
back a couple days later. I didn't (knowingly) change anything either time.

All help appreciated!
