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=yes does.
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 ...
