As I'm now over with the user commands, buttons, and about all the tweaks I could make to have DOpus working fine on both my home comp and USB export, I'm now focusing on some other parts of mighty DOpus!
I did some searches on smtp features on this forum, but still I don't seem to find any answers (just to mention, I found an unuseful topic with a lot of number guesses which was entertaining though 
), but nothing which could help me really understand the way it works!
First, with the searches I made, I found that the contact list is retrieved from Windows Adress Book, which leads to my first question....
I don't use neither Outlook express nor MsOutlook, but thunderbird, anyway don't really use the adress book anyway, but I guess if I could collect all the email adresses only on DOpus, it could be fine (just would like to try to see if it can be useful).
Alright, so 1st question is: can contacts be added manually? by typing, or drag & drop style 
?
2nd: I configured my different adresses (encrypted and not) to use on DOpus, but I never get connected when I use the connect button on the contact panel (both trying mailto:emul & smtp built-in). (I also used the Op Manager to try sending test mails)
3rd: Linking to the 2nd question.... what does the connect button on the contact list panel does exactly?
To see things globally, I don't really see the connections between all the smtp features DOpus has and how it works...
If someone could help clearing those things? would be so nice from you 
I guess I could have more questions, but I'm sure if I get some answers, a lot of other questions would be obsolete!
