Hello,

I know, it's not the fault of our beloved mutt, but maybe someone is or
was in the same problem and knows a solution...

We (my family) are member of a fisherman association and I have to send
mails to one of the head members in charge for youth training. He has a
Google mail account as <xxx...@gmail.com> and any mail gets rejected by
Google with the response below.

Any idea what I could do?

Thanks in advance

        matthias
