Sendmail podešavanja, mail server srednje veličine, deo 1

Dakle, dole navedena podešavanja su takva da se INBOX nalazi u /var/spool/mail, dok se ostale stavke (trash, sent items..) nalaze u /home/username folderu.

Ovo je /etc/mail/sendmail.mc fajl :

U suštini se u fajl niša ne dodaje, samo se zacrnjene stavke “odhešuju” a hešujuju se linije :
dnl #DAEMON_OPTIONS(‘Port=smtp,Addr=127.0.0.1…..
dnl #FEATURE(‘accept_unresolvable_domains…..
Od njega se pravi cf fajl sa komandom #/etc/mail/make

Pošto je ovo Fedora 16 (a ne RHEL4 na koj sam inače navikla), paziti na sledeću stvar :
# usermod -a -G mail user1
# id user1
uid=1000(user1) gid=1000(user1) groups=1000(user1),12(mail)
Da bi mail radio kako treba, potrebno je da svaki nalog ima još i dodatnu grupu “mail”.

Testiranje
Da bi se moglo testirati po portu 25 (110 za sada nije podignut), potrebno je sledeće :
*Podešen DNS zapis
*Podešen fajl /etc/hosts :
127.0.0.1 localhost.localdomain localhost.localdomain localhost4 localhost4 .localdomain4 localhost mail-2014
::1 localhost.localdomain localhost.localdomain localhost6 localhost6.localdomain6 localhost mail-2014
10.10.10.35 mail-2014.moj.domen mail-2014
*Podešen fajl /etc/mail/local-host-names :
# local-host-names – include all aliases for your machine here.
liste.moj.domen
mail-2014.moj.domen
mail-2014
*Podešen fajl /etc/mail/access+access.db :
Connect:localhost.localdomain RELAY
Connect:localhost RELAY
Connect:127.0.0.1 RELAY
10 RELAY
liste.moj.domen OK
Kreirati access.db tabelu koju sendmail čita :
#makemap hash access < access *Restart mašine.

Testiranje se vrši slanjem mail poruke iz komandne linije.
