[Lynx-dev] prerequisites or my config for email is correct?

[jindam, vani]

lynx on debian bookworm + xfce.
claws-mail is also installed.

my config for email:
SYSTEM_MAIL:sendmail -f jindam.vani@disroot.org -h disroot.org -r 
disroot.org -m SMTP

doubts:
* sent couple of emails to this
maiking list, but never received
any success or failure, mail is
not in the list
* do i need install or configure
anyother package?

regards,
jindam, vani
