Some 20+ years back it was fresh in everyone's memory t= hat the worm used sendmail bug and did a lot of damage on the internet (ever= ybody remembers the name of the guy who wrote the worm, right?).

Postfix is written (by brilliant guy Vietse Venema working then for IBM= ) from scratch with security in mind. It has several separate components. Mo= st notably: the daemon that is listening to the SMTP (SMTPS) port(s) and the= only component that is exposed to external world is very simple short code t= hat just communicates, checks what's necessary and accepts message for furth= er processing. It is very hard to have overlooked bugs in simple short progr= am. And that daemon runs as regular user. Sendmail (at that time at least) w= as one huge program (hence it is much harder to debug and make it clean) tha= t did everything, including listening to internet, and the daemon runs as us= er root. >=20 > That is really big difference security wise. >=20 > 2. This did not matter at the moment of making choice, but over years I be= came really appreciative of this: postfix has plain ASCII configuration file= s, which clear logic.

And I can (to an extent) edit sendmail's "low level" config f= iles directly (not only config file from which these are "compiled"), which l= oosely compares to editing assembly code vs high level programming language c= ode ;-) Yet, I still prefer postfix's plain ASCII config files. >=20 >=20 > I do not believe you made me write this. >=20 > Valeri >=20 >> Envoy=C3=A9 de mon iPhone >>>> Le 19 mars 2021 =C3=A0 11:06, Valeri Galtsev <galtsev@kicp.uchicago.edu= > a =C3=A9crit : >>>=20 >>> =EF=BB=BF >>>=20 >>> On 3/19/21 9:42 AM, Paul wrote: >>>> Or you could try not being lazy and fixing the bug yourself it=E2=80=99= s an open source software and you=E2=80=99re free to rewrite the kernel howe= ver you like so don=E2=80=99t play these games with us if freebsd is good en= ough for Apple in their build of xnu , Microsoft and Seagate, ARM, etc. , IT= SHOULD BE GOOD ENOUGH FOR JERRY, so don=E2=80=99t play this game with us an= d sendmail.org is the default mail server not postfix... >>>=20 >>> I join you on all counts... but I for one always replace sendmail with p= ostfix since forever (for over 2 decades).
