I retrieved an email message, selected Reply all, composed my reply
and pressed Send.
The system puts up an Alert box with the message
"An error occurred while sending mail. The mail server responded not
our customer. Please verify that your email address is correct in your
Mail Preferences and try again"
Several test mail messages to single recipients go out ok.
Powering down the modem for several minutes and a reboot of the
Operating system make no difference.
I can not send a Reply All to that message.
As Robert points out, there are incorrect recipient
addresses that you are sending to. It is your smtp ISP that
is sending you the error/reject message. It is an anti-spam
Here is my experience:
Prior to about two years ago, smtp ISPs would accept all
recipient addresses and send out the entire batch. After the
e-mail was sent, the ISP would return to sender those
Now, my experience is that ISPs verify each recipient
address in the sending queue BEFORE the smtp ISP server will
accept/send out the batch. For one thing, it extends the
waiting time between when the send button is clicked and the
time the "your mail has been sent" message comes on.
As was pointed out and as I understand it, the reason for
this pre-acceptance validation is to cut down on spam. If
any address is invalid, the message is not sent to any
One of my ISPs is a rascal --it simply sends back a message
similar to the one you posted. It does not identify the bad
address. In fact, if I have several bad addresses in a
batch, the ISP halts on the first one. When I am clever
enough to find it and resend, it will halt on the next one, etc.
My other ISP actually identifies the invalid address so it
is easy to repair or delete it.
In either case, it is probably intended to discourage
legitimate users from sending out large count multi
recipient messages, and to throw a log jam in the spammers
stream when the spammers use unvetted lists.
What I have had to do to overcome this verification
filtering when I encounter a rejection, is to send to a
limited number of recipients going down the list ten at a
time, until I hit the snag, and then send one by one in that
segment until I find the invalid address. Then I send out
the balance of the batch hoping that the one bad address was
the only one.
At least for me, for a while, my e-mail list has been
