Sendmail::Milter without threads

[Mark]

Hello,

I am interested in Sendmail::Milter on my FreeBSD 4.7R machine, but then for
Perl without threads. When I installed Perl, I compiled it without thread
support, as I believe thread support is still experimental in Perl 5.8.0.

So, is there a Sendmail::Milter that will not require a threads-enabled
Perl? Or is there perhaps another Perl Milter out there I could use?

Thanks,

- Mark
