I was not using the asynchronous (ARLIB) resolver, so I compiled dkim-filter version 2.7.0 with define(`bld_USE_ARLIB', `True'). After a week with the new dkim-filter, there are 25 netstat udp entries for my Upstream Nameserver #1 and 5 entires for the local nameserver, all for dkim-filter. None of my other milters leave these netstat udp entries. I use milter-greylist, milter-link, and milter-spiff, all use DNS lookups. The only other difference is that dkim-filter uses a port to communicate with Sendmail, while the other milters use UNIX sockets. DKIM does not release the tcp ports either. It has 6 tcp ports open to port XXXX on the local machine. Here are my Sendmail settings: Xdkim-filter, S=inet:[EMAIL PROTECTED], T=S:1m;R:1m Thanks for the help.
