Rich,
i too have received emails with COMMA SPACE between the
two people's email address's in the "TO" field and no quotes of any kind. *the 2 that received that same message*
That above was a "Gmail web client" sending a message to both a "Yahoo web email client". and "Gmail web email" recipient......
showing in the "TO" field that the message went to a........ GMAIL recipient (me) and a YAHOO recipient.
......it could be that it depends on the type of "email client tool" that is sending the message
as to what pattern of characters--is--displayed in the email clients receiving the message..... will be.
(for example, a "Web email client" like GMAIL sending a message to both a "yahoo web email" and "Outlook" client recipients , in contrast to an "Outlook desktop email client" sending a message to both a "yahoo web email client" and "Gmail web mail client" recipients.....
i would assume if i receive an email correctly, that shows in it's "TO" field that it went to me & also went to a second recipient and
that "second recipient email address" is shown there......then that second recipient also got the email message too.
Thanks
C
