Hi,

I manage several mailing lists on XEAMS.

When I specified multiple mailing lists in one email, the mail was not delivered.

For example, there are two mailing list LIST-A and LIST-B.
I can send email successfully to LIST-A.
I can send email successfully to LIST-B.
However, I cannot send email to LIST-A and LIST-B at the same time.

To: LIST-A  -> OK
To: LIST-B  -> OK
To: LIST-A, LIST-B  -> NG
TO: LIST-A Cc: LIST-B  -> NG

Could you inform me of solvent for this problem?

In "Manage Outbound Queue" menu, there is the unsent massage. However, by trying re-send the message, it shows an error like

Sender rejected. [smTrack=XML52,XML6!MEMBER1`DOMAIN-LIST-A@DOMAIN,LIST-B@DOMAIN]501 5.1.7 Bad sender address syntax . Typically, SMTP server's do not reject emails based on the sender's email. If the receiving end is under your control, check its logs to see why is it rejecting the sender.
