| | | | |
| − | amavisd-new
| + | Postfix on postiedastusagent (ingl. k. mail transport agent, MTA). Postiedastusagendi ülesanne on sooritada kontrolle, võtta epost vastu võrgust või lokaalselt ja anda edasi |
| | | | |
| − | clamav
| + | * postijaotusagendile (ingl. k. mail delivery agent, MDA) kirjade kasutajate postkastidesse jaotamiseks või kopeerida ise failisüsteemi |
| | + | * järgmisele postiedastusagendile |
| | + | * viiruste ja spämmi analüüsi süsteemile |
| | | | |
| − | Kogu süsteem toimib nii, et postfix annab kirja edasi amavisd'le, mis kontrollib seda kasutades amavisd'd ja smapsassassinit
| + | Postiedastusagent on epostisüsteemi keskne komponent, mis ühendab kokku kõik eposti liikumisega toimuvad tegevused |
