spaces in "FROM" field cause no delivery
|
|
|
| I am using IIS on w2k server. I drop files into the "pickup" folder to
deliver emails from a program. This has worked great for months.
Recently I noticed it didn't work anymore. Upon trial and error I found that
if the "FROM" field in the message had a space between words, the message would
be picked up but would never reach it's reciepient.
I can't recall when this started but I am always hitting the update site so
I suspect an update caused this behaviour. Nothing ever shows up in the badmail
or anywhere else for that matter. They just dissapear.
Can anyone confirm this and explain what is now happening?

| Where exactly is the "space" in the From: field?
Possibilities:
a) if the Domain in the From: address can not be resolved, the MS SMTP
server will *never* attempt to deliver it
b) the MS SMTP server is attempting to deliver it, but it is being gobbled
up somewhere else (e.g. destination mailserver perhaps)
There are no recent updates on WindowsUpdate that accept the functionality
of MS SMTP server as far as I'm aware. Without you posting some details, it
is impossible to debug this issue.

x-sender:info@mydomain.com
x-receiver:testbin@hotmail.com
From:System Message
To:Jim Bob
Subject:Tech - Network failure.
The server database is not available.
the space between the words in from line make the message just dissappear.
There is no domain in the From line, and I don't think there ever was. There
is of course in the "x-sender" line. but the from line can be anything.
I don't know what other details to add.
Would reverse DNS lookup enabled on the receiving end make the message fail?

| That is not a valid SMTP message as far as I can tell.
From: "John Doe" <john@somewhere>
To: "Jane Doe" <jane@somewhere>
is the correct way to do this (notice " around the name part). Also, you may
be able to use x-sender and x-receiver, but I don't know if a remote
mailserver will accept mail in that format.

| really? OK I'll try that today. I thought the FROM was just text that was
displayed. I didn't think it had anything to do with the actual addressing.

| Well what do you know. The quotation marks made all the difference! Thanks a
ton.
The x-sender and x-receiver seem to be very necessary, nothing moved without
them.
and the info in the brackets after the quotation marks also appear to be
optional, however I find that if I leave them off, my DSL provider (SBC)
tags on it's own ending. It adds "@mailapps1-int.prodigy.net" to the end of
the line.
Fascinating!
I know this worked for a while so I must have changed something in my
exchange end of things that blocked the IIS messages.

| You can get the definitive word on SMTP mail message formatting from here:
http://www.ietf.org/rfc/rfc0822.txt
I think anything beginning with x- is a vendor additional header. So, your
mail client may add it (eg x-generatedby: Outlook), or your mail server
might require it, but it's not part of the standard per se (it's just a
standard way of adding additional information).

| Pretty much right on the money, Ken. The x-sender & x-receiver tags are
added by the IIS SMTP server (maybe Exchange, too?) to all received
messages. It's MS's way of saving the contents of the MAIL FROM: and RCPT
TO: SMTP protocol commands. Remember that the RFC822 From/To/CC are just
for display purposes, a fact that most spammers rely on.

| But, but, but,
If I leave the x-sender and x-receiver off, nothing goes anywhere. At least that
I can verify.
and you are saying that they arent normally required? But yet my server does
require them?

If I add the bracketed email address after the quoted string, then I don't need
the x-sender etc. Is that right?
