Hi, I've been getting the below messages for quite some time now, and I also get them on postqueue -p. What can I do about it?
When I look at postqueue -p, the ID is 44C5E220E91 and when I do a grep, I get 44C5E220E91: to=<j.ack.c.hed.n.i.h.ao.m.a.a.l.in1.9...@gmail.com>, relay=alt1.gmail-smtp-in.l.google.com[173.194.70.27]:25, delay=96931, delays=96931/0.01/0.3/0.04, dsn=4.2.1, status=deferred (host alt1.gmail-smtp-in.l.google.com[173.194.70.27] said: 450-4.2.1 The user you are trying to contact is receiving mail at a rate that 450-4.2.1 prevents additional messages from being delivered. Please resend your 450-4.2.1 message at a later time. If the user is able to receive mail at that 450-4.2.1 time, your message will be delivered.

Did it bounce back and hence this message? If so, how can I prevent it?
