Dear Daniel,
Kindly checkout this code modification in apt.diff file attached with font
color green. After implementing new logic and handling outgoing qoutation
marks with escape character, the mail system on shell is working fine. I
believe that bug is fixed now and running efficiently on my system. Please
acknowledge our effort.
Regards
Qaiser Abbas
