Network connection issue (email mail merge function of OOwriter)

Hello,

First of all, thank you very much for your work (apps and support).

I have a problem with the email mail merge function of OpenOffice portable. When testing the email server parameters by clicking :

Tools > Options > OpenOffice.org Writer > Mail Merge E-mail
Test Settings

I get :

Establish network connection : Failed
Find outgoing mail server : Failed

Everything works fine with exactely the same settings under a static version of OO. Surprisingly (for me at least), it also works with portable OO when a static version is installed on the computer.

Thank's by advance for your help.
