Fetchmail delivers to the local MTA. So fetchmail itself isn't the MTA, it only acts as the transporter from an external mailbox to your local MTA, in this case Postfix.
Postfix seems to both receive and send email but its exact purpose is unknown, other than it is a MTA.
You said it, it is an MTA - a thing that RECEIVES and SENDS mail - but does not STORE mail or provide ACCESS to mail. .....So, like Fetchmail is the transporter of incoming mail does Postfix, how is outgoing email sent? Does Postfix use an inbuilt SMTP to transport sent mail?
[Procmail snipped, as it is deemed unnecessary, for now]
clamav is an antivirus mechanism which will be used as Windows clients(my laptop) will be accessing the IMAP store.
Yep. What would invoke Clamav, Postfix as it is the processor in-between the external source and internal IMAP store?
SpamAssassin is a spam combat tool and should be called into service before the antivirus.
However you want to do it, SA hammer to kill a fly, greylisting kills 98% of SPAM for us with no fuss, but your operating disconnected so you need to use something more clumsy.
So therefore the procedure would be?: 1) A cron job starts pppd and connects to my ISP. 2) Postfix sends any 'Outbox' email. 3) Fetchmail then receive all incoming mail 4) Fetchmail passes it with what to SpamAssassin 5) SpamAssassin passes the messages using ?......? to clamav to check for viruses. 6) Clamav passes the checked email to the IMAP store using ?,,,,,,?
Postfix should encapsulate both SA and CLAM, you shouldn't have to worry about them. So Postfix will invoke both SA and Clamav and then pass the mail to the IMAP store.
putting the spam into the Thunderbird Junk folder and the virus messages into the Deleted Items, leaving all messages UNREAD.
Beats me. ok, As long as the spam and virus messages coming into the Inbox have a certain subject, I can setup a Thunderbird filter.
Sendmail isn't nearly that scarry, except for ninnies that can't spell M-4. No one edits sendmail.cf. Why would I need sendmail, surely I have all the above packages to receive(Fetchmail) and send(Postfix) mail?
