I think you experienced same problem as me of about a year ago. So
check thread starting with following message.

I can't help you with Postfix configuration I'm afraid, but you'll
probably need to check that you have it right.

Useless directive - applies to Unix sockets.

I've never actually checked, but I'd be surprised if you can use
_both_ a local (Unix) socket _and_ a TCP socket for clamd, and since
you appear to have configured the milter for TCP then I think you
should remove all these local socket directives. But you might be
better off using Unix (local) sockets. I do not like the use of
the word 'local' applied to sockets, I think it's confusing, but
we have what we have.

> TCPSocket "3310"

Remove the quotes.

Have you checked that clamav-milter and clamd actually start and
continue to run? Do you know how to do that?

By comparison with many system administration tasks, it was simple.

The messages are very clear. They mean what they say.

I have already told you that I cannot help you with Postfix issues and
these are very clearly Postfix error messages. The communications
between Postfix and the milter seem to be broken. Typical packet
lengths are kilobytes, you seem to have gigabytes. But this may be a
symptom of a broken installation, and given that you are evidently out
of your depth that would not be surprising. In my last I also said
that you might be better off using Unix sockets and not TCP sockets
for the milter communications, since the processes all seem to be on
the same host. For someone who is obviously very new to this, Unix
sockets will probably be safer than TCP sockets because you will not
need to secure Unix sockets like you would need to secure TCP sockets.
My guess is that you do not know how to do that, nor why you need to.

The best advice that I think I can give to you now is that before you
do anything else you should spend some quality time reading about the
dangers which face all Internet-connected systems generally, and mail
systems in particular. You do not have the necessary experience, and
at present, if you try to run a mail service connected to the public
Internet, I fear that it will be an accident waiting - probably not
for very long - to happen.
