[TYPO3-english] problem with directmail, tc_directmail and newsletter extensions

[Piotr Burda]

Hi
On one TYPO3 installation i have strange problem with directmail,  
tc_directmail and newsletter extensions.
When i try to send a newsletter using:
1. direct mail - i have error message: The HTML content could not be  
fetched
2. tc_directmail: Content too short. The content must be at least 200  
chars long to be considered valid.

on same server other TYPO3 installations and newsletter extensions are  
working fine.
allow_url_fopen is on
allow_url_include is off

some infos about installation:
