Actually, I chose to do it that way because using getmail to collect
incoming messages avoids having to open any ports in my firewall.

I run my own internal Postfix MTA for two additional reasons:

- I have a database-based mail archive which gets fed via a Postfix
  'always_bcc' directive. I ensure that all my incoming and outgoing mail
  passes through that MTA. Why do that? Because I thought that it should
  be a lot faster to find an e-mail by searching that database than by
  looking through huge email folders in an MTA - and it certainly is.
  Any matching email among the 184,000 in the archive will be found within
  10 seconds and can be inspected in the search app or forwarded to my
  MUA so attachments can be saved and/or it can be replied to.

- The archive also acts as a whitelisting engine: I wrote a Spamassassin
  rule that whitelists any e-mail whose sender is recorded as having
  received mail from me.

That too. I also run an internal HTTP server (Apache) which is an
extended bookmarking system, provides no-hassle access to a growing
collection of images and documents in a variety of topics, as well as
being a convenient place to publish my externally visible websites, which
are exported to a webhost via FTP.

I save myself a lot of hassle by using external hosts for my websites and
domain names and by routing all incoming and outgoing mail through my
ISP's mail server.
