For what it's worth, the next release of RT will include a --ca-file
option you can use to specify the specific cert.  It's equivalent to

> *root at linux:/opt/rt4/bin# *export PERL_LWP_SSL_CA_PATH=/etc/ssl/certs

If you'd like to submit a simple patch to rt-mailgate that also adds
support for --ca-path, I'm sure we'd apply it.

I do wonder why the OpenSSL library underlying the Perl library isn't
finding your cert in /etc/ssl/certs like I'd expect it to.
