RE: Email oddity -- MIDRANGE-L

Thanks for the article. Maybe, it >will< be resolved today. Just (apparently) have to supply the answers, as well as the questions when asking some support people for help.

I don't know if you had noticed that cox.net was specifically mentioned in
that article, but in an ambiguous way. Thought it was interesting anyway.
I hope it's resolved.

I had suggested that. Person I was working with was just a little
reluctant to listen. I appreciate your explanation. I did suggest
that he format the return address exactly as his Outlook return address
was. What I got was a rather odd address.

Thanks for the confirmation.

My $0.18 says that this is the issue:

by a host with no rDNS <<

The host that sent that message presents itself as an IP address, but
reverse DNS (translation from IP address to DNS) is not possible.

Many ISPs

will reject such mail since most spam has that attribute. It is

likely that

Cox is one of those. This was the rule that VZ finally relaxed a few

years

ago, that had stopped that US site's mail from being received.

Here's a research starter for you:

Message that >is< sent and received by Cox is produced by Outlook.
Message sent via SNDEMAIL, which forwards to the email server, is

just

typed in.

Below is a sample. I have obfuscated part of the domain, and IP
addresses. Nothing more.

While doing that, I saw in the last line:

-------------------------------------------------- 0.14

MISSING_MID

Missing Message-Id: header 0.10 RDNS_NONE Delivered to trusted

network

by a host with no rDNS 0.50 BSF_SC5_MJ1963 Custom Rule MJ1963

Yet, I received it. Which implies my ISP is more tolerant than Cox.
This was produced by the SENDEMAIL command and the API that it

calls.

Is that message stating what is actually wrong? And, if so, how is

it

fixed? Is this in the SENDEMAIL processing, or the main Windows

email

server?

How is the message being created? Is it possible to share the

headers of that message (sans any personal details) with the group?

I've seen a couple of issues like this. One was at a large US

Government site, that was black-listed by Verizon. Not pretty, and
only a policy change at Verizon cleared it up. I don't remember

the

details behind the isssue - had something to do with sender domain

or

sending server's CNAME record, I think, though. Anyway, the

apparent

effect was that any mail that server sent could be received, except

by

VZ customers.

The other is DNS/Routing, though this is pretty rare. A DNS at

one

installation had invalid information for a large recipient server,

like

Cox.

Might want to check the spam rules and any mailbox options at the

Cox

site too.

Good luck.

Guy here attempts to send an email from the i to his personal

my

personal email and all is well. He can send an email from

Outlook

to

his Cox account, and that goes through as well.

I have suggested to him that Cox may be doing address

verification,

and

that what he has chosen for a sender name does not match,

exactly,

the

registered name in the mail server. The i is NOT the mail

server.

Any ideas as to why a mail generated from Outlook would go

through

to

Cox, but not from the i?

MAILTOOL would be nice, but not likely an option.
