yes, it worked. (You had the list address in there.)

Good, GpgOL should work with this setting.

Also good.

Is it an option to just attach the file to the email?
With Gpg4win2 it will be encrypted as part of the email encryption.
(Technically the new GpgOL will use PGP/MIME as strongly recommended by 
OpenPGP. So this will sign and encrypt attachments on the email by default.)

Ah, okay, the file manager is GpgEx that you are using.
You are saying that the resulting name on the target system is not directly 
recognised by the explorer. (So context menu and double click will not open 
it.) I am quite sure this is a windows setting that could be changed to also 
recognise the file types.
(I cannot currently check, maybe another windows user as a hint here.)

The filename of the target system depends on the sending and receiving email 
systems. Technically their method of how to attach the file in the MIME 
format. This is something that could be broken for your process, but I did 
not understand that you were using the filebrowser to encrypt the file before 
you attach it.

Did you try to rename the file before attaching on the sending system, after 
using GpgEX to encrypt it?
