After contacting my e-mail provider, they tell me I can not longer use thunderbird. In the past I did not have problems. When I send a mail with an attachment the system completely blocks and I receive the following message.

As a workaround you can try this: At the top right of the Thunderbird window, click the menu button > Options > Advanced > Config Editor. Confirm the "I'll be careful, I promise!" warning. Type "mime" into the filter box. Double-click the pref "mail.strictly_mime" to change the setting from "false" to "true". Close out and try again sending the message.
