ABRA Flexi on Linux supports only Mozilla Thunderbird for sending emails.
What is happening
Thunderbird opens when sending, but the email does not contain an attachment (PDF).
Cause
The environment variable MAILER, which determines which email client Flexi should use, is not configured correctly.
Solution
Set the MAILER variable to Thunderbird.
Option 1 – system-wide setting:
Edit the file:
/etc/default/flexibee
and add:
export MAILER=thunderbird
Option 2 – user-level setting:
Add the same line to the file:
~/.profile
After making the change
restart the application (or log out and log back in)
