Hello, Please see this, as to me it looks like it should work as mutt at least works with this type of addressing:
mail -E"set sendmail=sendmail:/home/admin/bin/sendmail" -s "Subject here" -a "From: Jean <s...@example.com>" "bugs@gnu.support <bugs@gnu.support>" --content-type=text/plain < /run/user/1001/text-file mail: Cannot parse address `bugs@gnu.support <bugs@gnu.support>': Malformed email address I think that first part of this below: "bugs@gnu.support <bugs@gnu.support>" ^^^^^^^^^^^^^^^^ should be thought of as name for the email address if there is <s...@example.com> as second part, isn't it? I may see that if I put it in double quotes like "\"bugs@gnu.support\" <bugs@gnu.support>" that in that case it works. What is correct here to do? Should `mail' process it without double quotes? Should I only use double quotes?
