Hi all. I've gotten emails back in the past that say MAILER-DAEMON and it wasn't deliverable for three hours, etc., and most times there is a problem on the other end or their mail box is full or whatever. But I was wondering if it could also mean that I've been blocked, or would I get a different type of message actually telling me that I'm blocked?

 

I do not think that means you have been blocked.

 

with most isp's, if you were blocked you would get a message on the lines of "the intended addressee has refused to accept email messages from you" or something to that effect.

 

it also could mean that you may have misspelled the email wrong, or like has been said before that the mail box is full but if you are being blocked you would get a message stating that you are being blocked try resending the email to the person again and see what happens. good luck hope we have helped you out.

 

Hi.... I sent it again and it returned again. I know the address is correct. I guess I'll keep trying. I just didn't want to keep doing so if I was, in fact, being blocked. Thanks for your replies. They were very helpful.

 

Do you know how to find the email's headers? If you can get to them I can tell you exactly what happened.

 

Hi FTE.... the only 'headers' that I'm familiar with are on cars.... LOL.... but I'll send the whole message I got from the DAEMON (minus the email addy) which is as follows:

The original message was received at Sun, 20 Jul 2008 04:18:20 -0400 (EDT)
from imo-d05.mail.aol.com [172.18.150.229]

*** ATTENTION ***

Your e-mail is being returned to you because there was a problem with its
delivery. The address which was undeliverable is listed in the section
labeled: "----- The following addresses had permanent fatal errors -----".

The reason your mail is being returned to you is listed in the section
labeled: "----- Transcript of Session Follows -----".

The line beginning with "<<<" describes the specific reason your e-mail could
not be delivered. The next line contains a second error message which is a
general translation for other e-mail servers.

Please direct further questions regarding this message to the e-mail
administrator or Postmaster at that destination.

--AOL Postmaster

----- The following addresses had permanent fatal errors -----

----- Transcript of session follows -----
451 4.4.1 reply: read error from smtp.******.com.
<*****@*******.com>... Deferred: Connection timed out with smtp.*****.com.
Message could not be delivered for 3 hours
Message will be deleted from queue

 

It's a 451 error. The likely answer is the ISP you are sending from is being blocked at AOL, you as the sender are being blocked by the recipient, or your ISP has some serios network difficulties.

Thanks so much FTE Herman. I learned something new today. And the link will come in handy for any future MAILER-DAEMONS.
