Snow Leopard Server Mail Settings?

Hi,

I'm having some problems with Snow Leopard Server email (mail bouncing =
or taking a long time to get in, an hour or more, in some cases).

Can someone please help with clear definitions for (and the purpose of) =
these settings in the Mail Service > Settings > General tab in Server =
Admin?

1. Domain name: =20
Enter the local Internet domain name.

What exactly is this meant to be (and how is it used)?

Currently this is set to "local"
I only have one server that runs mail and web behind our ADSL =
modem/router
Hopefully, ports are forwarded as appropriate from the modem/router to =
the server
I do have an internal DNS setup, with the same domain as external for =
when clients are connected locally.

2. Host name:
Enter the Internet host name of this mail system

What exactly is this meant to be (and how is it used)?

Currently this is set to "mydomain.com"
I would have thought that the Internet host name would have been =
mail.mydomain.com as in the MX record?
I think I have used that in the past but my email addresses then looked =
like name-i4yH9JU3wRtWVPTZF4YnfwC/[email protected] :-(


3. Mail > Settings > Relay=20

With regards to the delay of emails getting accepted (when they don't =
bounce and only from some servers it seems, e.g. Apple mac.com delivered =
immediately)

I thought this was caused by my using some  "junk mail rejection servers =
(realtime blacklist)"

However, I've check again and I no longer seem to have any of these =
configured (are they recommended? which ones?) so something else must be =
slowing down the mail delivery. =20

I notice in the mail.log lots of entries like this:

> Mar  6 12:09:06 server postfix/smtpd[52216]: connect from =
mailserver.easterncontrols.com[70.90.14.220]
> Mar  6 12:09:07 server postfix/smtpd[52216]: NOQUEUE: reject: RCPT =
from mailserver.easterncontrols.com[70.90.14.220]: 450 4.7.1 =
<info-3Q2Tfjf0mew0n/[email protected]>: Recipient address rejected: Service is =
unavailable; from=3D<[email protected]> =
to=3D<info-vF6D3zRCt/[email protected]> proto=3DESMTP =
helo=3D<mailserver.easterncontrols.com>
> Mar  6 12:09:08 server postfix/smtpd[52216]: lost connection after =
DATA (0 bytes) from mailserver.easterncontrols.com[70.90.14.220]
> Mar  6 12:09:08 server postfix/smtpd[52216]: disconnect from =
mailserver.easterncontrols.com[70.90.14.220]

I thought this was the realtime blacklisting.

I also see lots of these:

> Mar  6 12:10:42 server postfix/anvil[51922]: statistics: max =
connection rate 5/60s for (smtp:68.203.211.226) at Mar  6 12:06:03
> Mar  6 12:10:42 server postfix/anvil[51922]: statistics: max =
connection count 2 for (smtp:134.7.73.150) at Mar  6 12:04:27
> Mar  6 12:10:42 server postfix/anvil[51922]: statistics: max cache =
size 4 at Mar  6 12:05:25

Are these just spam sites or is something wrong my end?

I have checked my email service from outside, using the Web sites that =
check, and it all seems fine - no open relay, mail server matches =
reverse dns, etc. =20

Thanks in advance for any assistance.

Cheers,
Ashley.
