Hi, I'm seeing the same error even on older versions of FreeBSD (thus sendmail). I also tracked the issue to SERVFAIL response to AAAA request. According to sendmail docs, the WorkAroundBrokenAAAA option should work as a workaround, but clearly doesn't. Compiling sendmail with NO_INET6=3Dyes d= oes. Setting mailertable entry for (broken) destination domain to relevant IPv4 address should also work (athough not tested). I haven't searched sendmail archives, but since it's mentioned in the docs = =2E..
