DKIM套接字问题

Question

I have a problem with dkim-milter.

My maillog file is filled with logs

Dec  5 23:59:59 NS1 dkim-filter[31424]: Sendmail DKIM Filter: Unable to bind to port inet:20209@localhost: Address already in use
Dec  5 23:59:59 NS1 dkim-filter[31424]: Sendmail DKIM Filter: Unable to create listening socket on conn inet:20209@localhost
Dec  5 23:59:59 NS1 dkim-filter[31424]: smfi_opensocket() failed

I suspect that the problem is related to Dkim-filter.conf and line:

Socket                  inet:20209@localhost

It looks like something is allready runing on that port so I can't bind it again.

How can I change this and make DKIM running without errors?

Answer 1

port 20209 is already in use, maybe an old zombie dkim-milter?

netstat -nlp | grep 20209 will help you find out whats blocking the port
