[Resolved] Mail() 550 error.

Kold

Hello.

I am using the mail() function to send emails, and commas to separate email addresses.

Warning: mail(): SMTP server response: 550 unknown user < [my email address] > in [filename] [line number]

The email address is valid. I am only receiving this error once, despite there being 2 others (comma separated) in the 'to' part of the function.

Does anyone have any ideas as to what the error could be about? Also, the error did not occur for the other (first two) email addresses in the string, does this mean they would have been sent?

Thanks
K.

If it is behaving properly then yes, the other recipients sholud jave received it. But acid test: ask them.

Your own copy could have bounced for several reasons. Where is it located? The 550 means that your host smtp server refused to accept the email because you were not in it's list of users: in thoery. In parctice, it could mean that your host smtp interpreted the email as spam and blocked it, or that your post q was full, etc. Could even mean that it was too busy to handle any more mail.

More likely there is some error in the actual address string you have added to the To: list.

Thanks.

I was going to add the code, but as i say, one-off emails were being sent fine.


  If($MailResult = mail($Address, $Subject, $Message, $headers)){
    $Result = "Sent";
  }else{
    $Result = "Not Sent";
  }

**Having looked at this again, wouldnt this always return true? Even if mail() returned 0, it would still be assigned to the variable, returning 'true' to the IF?

The headers look like this;

  $headers = "MIME-Version: 1.0\r\n";
  $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
  $headers .= "From: $admin_email <$admin_email>\r\n";
  $headers .= "Reply-To: $admin_email\r\n";

I have asked the owner and none of the 3 users received the email. I did my own test and i received all of the emails fine, so there is not a 3 email limit.

I have checked the $Address and the string looks fine.

I will make it create a text file to save all of the parameters of the function just in case. (However i tried to break my test script and couldnt get this error).

Just to note that the only other time i have received this error on this server is when the $Address variable was blank, which, if you look at the error from the first post, resulted in there being nothing between the '< >' (this time there was an email address between them).

Thanks for any help/suggestions!

A brief comment on the "\r\n" in headers:
Recent email scanners (virus scanners) working on mail servers will refuse to deliver any mail containing the "\r" character in header (your mail will probably bounce off with "Disallowed MIME characters found in headers" comment).
This is true for Qmail-Scanner and F-Prot Antivirus for Linux but for others most probably too.
Hence use "\r\n" in headers ONLY when you send you email using the mail() function via Windows-based SMTP server - otherwise just use "\n"

The \r\n or \n issue...

I'd been pulling my hair out over this one for months. The problem I had was mail sent with mail() was being delivered fine to my account, but other users (with accounts on an MS Exchange server) saw the attachment text in the message body - however when I used Outlook to view my (non-Exchange) IMAP folder they loaded fine.

Because \r\n seemed like the 'right thing to do', based on the comments about the RFC etc the last thing I tried in order to fix the problem was replace them with \n... However that's exactly what fixed it.

I don't know how the RFC explains this one, but when I did change all the \r\n's to \n it worked perfectly (and when I got a chance to look at an outlook user's broken emails, everything was infact doubly spaced, i.e. \r\n was converted to \n\n somewhere along the line).

So I suggest if \r\n isn't working for you, just try \n. It might not be correct by the RFC, but 90% of my users not being able to read the attachments wasn't a better option...

Hope this helps anyone who's got the same problem."

Thanks.

I have changed it to just \n and i will see if it works.

My previous question about my 'If' can be ignored, my log file shows that it works fine 🙂

I will let you know what happens...

Thanks.

Nope, \n didnt solve it. I will add the .biz address to a test script and see what happens...

[EDIT]
hmmm, mail server doesnt like the .biz email address :eek:

[edit #2]
I asked them to remove .biz and it worked!!!
I wonder why :queasy:

Thanks for your help!
