ISPConfig 3 - Mail Flow
 
Can someone describe exactly how mail flows through the standard ISPConfig 3 setup? I have investigated the configs to some extent and have a basic idea, but there seems to be some redundancy I don't quite understand.

Here is my basic understanding:

Postfix receives mail, forwards to amavisd-new, which then scans with clamav, and spamassasin, and then sends back to postfix.....

Does postfix then send to maildrop for delivery? How can one verify this?

----
Is virus scan and spam filtering enabled globally by default unless turned off in a domain?
----

Also, how is getmail used exactly?

If this is documented reasonably straight forward somewhere I would be happy for a pointer.

Thanks,
Sean

Take a look at the mail log.

Yes, but this depends on the default settings for amavisd of your email distribution.

Getmail is used to fetch mail from external pop3 or imap accounts.

It's nice to know that I sleuthed it out correctly, but it is even better to have confirmation.

Thanks,
