in message
When sending email to a distribution group, one person in the group
is over
quota and it kicks back my email. It doesn't go to anyone if one
person is
over quota. What do I need to do.
Huh? For SMTP, the process is:
- The e-mail client generates a RCPT-TO header for each recipient that
it sends to the outbound mail host (i.e., your mail server). For N
recipients, the mail host gets N different RCPT-TO commands.
- The e-mail client then generates a DATA command, the server sends
back +OK to announce it is ready to accept the data, the client sends
the data of the message (headers and body), the client sends a "." by
itself on a line to indicate the end of transmission, and the server
sends back +OK to show it got the data okay.
- The SMTP server then sends a SEPARATE copy of the same message to
each recipient specified by the RCPT-TO commands.
The client sends a list of SEPARATE recipients to the mail server and
ONE copy of the e-mail. It is then up to the mail server to send that
same message to each recipient. At that point, it is up to the mail
server to send out your one e-mail to the list of multiple recipients.
You have no control at that point.
If you are getting back an NDR (non-delivery report) saying that one
of your recipients was over quota which means your mail server could
not deliver your message to that receiving mail host, it is only
bitching about that one recipient, not any of the other recipients.
You have no control over how the mail server operates. You can only
have your e-mail client hand off one copy of your message (via DATA
command) after already handing off a list of recipients (via RCPT-TO
command) to the mail server and then the mail server is supposed to
handle the separate delivery of each copy of your message to each
recipient in the list - but there should be no dependency on delivery
between the recipients.
Getting back an NDR for one recipient from an e-mail sent to multiple
recipients only means that one recipient did not get your e-mail.
