My LogWatch - for 24 hours - shows:

Unknown local users: Total: 122
Relay attempts from known spammers: Total: 93
Rejected incoming mail (my criteria): Total: 38

(a couple of other types not included here) Total: 4

Summary: Total Mail Rejected: 256

that maybe, but lots of email servers will simply not send to it due to
a lack of mx records, and most should not be accepting mail from you due
to a lack of mx records, and of course loads simply dont accept email
from dynamic ip's etc etc the list goes on and on

Proof in your statement? conjecture, that I believe does not stand up to
fact, I can send to gmail, yahoo, msn and hotmail without issue. I have
yet to see or hear of such a problem elsewhere as well. I work as a sys
admin with mail servers sending and receiving in excess of a million
emails a month so my experience does not agree with your assessment.

Most servers do not care what they send TO, more are concerned with what
they receive FROM. Problem is scale, there are rbl services that you can
subscribe to to block cable and adsl modem pools, but by default I do
not think many do, a greylist is more effective and workable IMHO (see
below).

I do not have a not a dynamic IP, it is an agreed static with my
provider ssince 1999, more accurately I think you mean from a modem pool....

At work we block IP's from non-NZ modem pools, that stopped 292,000 spam
last month....so I can understand why email servers would though.

We do not block NZ modem pools as lots of small businesses now run email
servers off adsl and cable connections, so we simply cannot, it would
cause a riot. We do insist that the mail servers are in a resolvable
domain and that things like helo msg contains the FQDN.

I certainly have zero problems mailing anywhere I want at present,
though soon I will be getting a proper domain and hence MX record, as I
agree I need to become more formalised both in that I want my own domain
and that sooner or later things like no MX record and SPF will make my
present system un-workable. All due to spammers!

Mail does NOT need an MX record. It can and often does use an A
record.

You are joking right?

You havent even managed to setup your mail server correctly... it has no
mx records!! come on, be sensible.

i know for a fact there are servers that would reject mail from you,
mine would for a start, one cause you are on a dyndns domain and 2
because you havent even set up your server properly (no mx records)

i can direct you to some mail server guides for dummies if you want,
that explain about setting up mx records etc

MX records are not essential for MTA's to work, proof is below.

The server is correctly setup, its the DNS that is not. An MX record
tells the originating server what host to connect to within the domain
to deliver mail, not where the mail is from. I have a wild card for my
domain which achieves the same thing.

Point in fact, we have 3 SMTP servers (shortly to become 4), the MX(s)
are the incoming server(s) (x2), the outgoing server is not a MX record,
yet guess what mail works.

> i can direct you to some mail server guides for dummies if you want,

lol, no thanks I know how to set them up in fact I think you need some
education.

Take this domain, note terror is not in any shape or form in the MX records.

Terror is the outgoing server, then followed by a MX record lookup for
the domain,

[thing@kaitan thing]$ nslookup
> terror.vuw.ac.nz

Server: 192.168.0.100
Address: 192.168.0.100#53

Non-authoritative answer:
Name: terror.vuw.ac.nz
Address: 130.195.86.21
> set type=mx
> vuw.ac.nz

Server: 192.168.0.100
Address: 192.168.0.100#53

Non-authoritative answer:
vuw.ac.nz mail exchanger = 10 logan.vuw.ac.nz.
vuw.ac.nz mail exchanger = 5 mitre.vuw.ac.nz.

Authoritative answers can be found from:
vuw.ac.nz nameserver = circa.mcs.vuw.ac.nz.
vuw.ac.nz nameserver = pubsec.domainz.net.nz.
vuw.ac.nz nameserver = totara.its.vuw.ac.nz.
vuw.ac.nz nameserver = downstage.mcs.vuw.ac.nz.
vuw.ac.nz nameserver = rata.vuw.ac.nz.
logan.vuw.ac.nz internet address = 130.195.86.22
mitre.vuw.ac.nz internet address = 130.195.86.116
circa.mcs.vuw.ac.nz internet address = 130.195.5.12
pubsec.domainz.net.nz internet address = 202.46.160.4
totara.its.vuw.ac.nz internet address = 130.195.2.249
downstage.mcs.vuw.ac.nz internet address = 130.195.6.10
rata.vuw.ac.nz internet address = 130.195.2.11

>server rata.vuw.ac.nz

Default server: rata.vuw.ac.nz
Address: 130.195.2.11#53
> vuw.ac.nz

Server: rata.vuw.ac.nz
Address: 130.195.2.11#53

vuw.ac.nz mail exchanger = 10 logan.vuw.ac.nz.
vuw.ac.nz mail exchanger = 5 mitre.vuw.ac.nz.

By your reasoning most large mail systems would not work, guess what
they do.

I think from memory that an A record maybe essential, think it says
somewhere in the bat book, I forget, Ive read so much stuff on SMTP and
DNS in the last 4 months......

let me find that guide for dummies on setting up a mail server
i think step 1 was setting up mx records



The point is, that many servers to mx checks because hey guess what?
mail servers are supposed to have mx records pointing at them.

and yes a lot of mail servers will send to a records if they can find no
mx record, but some wont.
and yes lots of mail servers will accept mail without doing any checks
on mx records, but some will.

so why would you setup a domain with no mx records? unless you are lazy
or stupid, or want to take the risk of domains simply dumping messages
from you silenty or simply rejecting it.

i deal with mail server customers everyday that ask why a server is
rejecting mail from them, loads of times the reasons is due to lack of
mx records

anyway if you are having no problems then you have been lucky i guess,
but also remember mail servers often simply vanish messages these days
instead of outright rejecting them so you wouldnt even know if the
server has dont checks on you or not

i can direct you to plenty of infomation on this if you like

Well, yeah, eventually! <grin> An MX record is a type of alias (CNAME
if you like) and *must* refer to another record which *must* be an A
record.
