I'm using KDE on debian.
On Kmail application, while sending a mail I got the following error:
Failed to get D-Bus interface of
mailfilteragent.
But, inbox is synchronized properly. Previously, I had 2 problems regarding this app; now it reduced to one. Use it as this is lightweight than Thunderbird, Mailspring. Weeks ago, I used the Mailspring app, the only problem is it sends the message twice.
So, Is there any solution?
