MUTT Notes

Masquerade

• Creating the ~/.muttrc file was critical.

set use_envelope_from = yes
set edit_headers=yes
set use_from = yes
set from = "user_name@domain.com"
set realname = "user_name"
set hidden_host=yes

• At this point I also modified sendmail. Though I don't think this was needed.

FEATURE(always_add_domain)dnl
FEATURE(`masquerade_entire_domain') dnl
FEATURE(`masquerade_envelope') dnl
FEATURE(`allmasquerade') dnl
MASQUERADE_AS(`domain.com.') dnl
MASQUERADE_DOMAIN(`domain.com.') dnl

• From this point I was able to send emails through my relay and to Office365
