Email Rejections

[PetrolTed]

I'm getting a few messages like this recently:

email thingy said:

The original message was received at Fri, 30 Jan 2004 08:06:30 -0000 ----- The following addresses had permanent fatal errors ----- <*********.plus.com> ----- Transcript of session follows ----- ... while talking to mx.core.plus.net >>> DATA <<< 550 Most messages without it are spam, so your mail has been rejected.

What does it mean? Without what?

Well, there's egg and bacon; egg sausage and bacon; egg and spam; egg bacon and spam; egg bacon sausage and spam; spam bacon sausage and spam; spam egg spam spam bacon and spam; spam sausage spam spam bacon spam tomato and spam;

...You can't have egg bacon spam and sausage without the spam.

Seriously though, I've never seen that one before. The arrows are pointing to "DATA" so maybe it thinks there's no content?

Are you sending the mail as Plain Text, HTML, or both?

[Plotloss]

Yeah thats what I thought, looks like its been rejected due to lack of 'body'

[Bonce]

Yep, the last two emails I've had from PH have no plain text body. It's possible to send mails containing both version to cater for people living in the dark ages - mail me if you want a code snip.

In an effort to stop spam, alot of the larger ISPs are being v/tight on mail now.

For example AOL wont let you relay unless your MX server has reverse DNS.

Seems these wont let you relay unless your have plaintext inside your email.

Alot of spammers send just HTML based emails, forcing users to have to switch to HTML to see them, and thus launching their malicious / pr0n content.

We said we wanted less spam, this is how they plan to do it, lock down mail so hard, that alot of legit mail doesnt get thru. Still, once everyone complies, it should make it a safer world....

Thanks. I'll check out what I'm sending.

I thought it was just plain text in those particular emails.

Ted,
Error 550 is Requested action not taken: mailbox unavailable e.g., mailbox not found, no access.

Just for fun most conversation between a mail client and a server go along the lines of below. As you can see a 550 response doens't always mean the mail can't go through.

Client: MAIL FROM:<[e-mail]>
Server: 250 OK

C: RCPT TO:<[e-mail]>
S: 250 OK

C: RCPT TO:<[e-mail]>
S: 550 No such user here

C: RCPT TO:<[e-mail]>
S: 250 OK

C: DATA
S: 354 Start mail input; end with <CRLF>.<CRLF>
C: Blah blah blah...
C: ...etc. etc. etc.
C: <CRLF>.<CRLF>
S: 250 OK


best
Ex
