Thank you Vojtech for your interest and your response!
Yes, the process ashMaiSv.exe is running. If I left-click on the Avast-Icon in the systray, it shows me all the services and the Internet / Mail-Sertvice is shown as active. I can configure it from there.
The main question here is:
Is Avast! able to connect with the mailserver and log in there in order to fetch e-mails?
I think, it cannot, beacause for logging in at gmx you will have to enter a username and a password. In the describtion of Avast! help and the thread about avast4.ini I only could see, that they log in with username#mail.server.com
Or is it the e-mail client Opera M2, which perhaps is not able to correspond properly with avast via the 127.0.0.1.
Or is it Opera M2 which cannot submit password after Avast has begun with login and by this the login procedure will not be completed.
I don't see a feature, to switch on something like a login or a connection protocoll, so that I can see, at which part things get wrong!
In Opera M2 as in other mail clients I can fill in username, password and of course the mailserver (SMTP and POP3 / IMAP). In Avast! I only can fill in username#mailserver...
As I allready have posted, I tried all the possible combinations and none did work! As far as I understand, it should work properly, if I set mail.server.com in avast4.ini and then set the account in the mail client with server = 127.0.0.1 andfill in in Username the username#mail.server.com and password.
Is that right?
