After posting, I became aware also that I was confusing real-time =
blacklisting with greylisting.  I have used real-time blacklisting in =
the past as well but I believe I turned it off for some reason.

=46rom what I read it sounds like a good thing to have greylisting - =
IIRC it did reduce my spam significantly, apparently because spammers =
don't retry bounced emails - so I will leave it on.

I am sorry to be pedantic (because postfix is ;-) but do you really mean =
any domain?  I receive mail for a handful of domains?  How will it be =
used?  E.g. I don't want email replying from one domain for another.

As I mention, I current have this as "local"  which has seemed to work =
fine, since I guess it is a (local) domain from which the server =
receives email for.  Can I leave this as that?

one for the domain in #1.

By public host name I guess you mean FQDN?

I have set this as the public host name of the server (which is the MX =
record) mail.mydomain.com but then I seem to remember emails replying =
with addresses like name-i4yH9JU3wRtWVPTZF4YnfwC/[email protected], which didn't look very good.

I currently have this as "mydomain.com" and it seems to work ok (maybe). =
 Can I leave this as that?  Sorry, again just trying to be clear.

public name. Some servers will reject mail that doesn't have a correct =

DNS for the IP addresses that they give out to their customers.

I have that thanks.

Finally, if you don't mind me asking another question, in Mail Server > =
Advanced > Hosting, there are another two setting as well that are not =
very clear:

1. Include server's domain as local host alias
Checked on.

What does that actually mean?  I can't parse that sentence (fragment)?

I currently have all sorts of things in here, e.g. mail.mydomain1.com, =
mydomain1.com, <public host name>, mail.mydomain2.com, mydomain2.com ...

2. Enable virtual hosting
Checked on.

What does this actually do? =20

Until today I think I had that on but with out any entries, and I =
thought I was hosting virtual domains just fine.  It has all worked =
fine. =20

Today I added  mydomain1.com just to see if it would fix things.

Do I need this?  What does it do?=20

Sorry for all the questions, and thanks again for your assistance.

Cheers,
Ashley.
