Hello,

afaui POODLE should not be a reason to to disable SSL3 /for/ /SMTP/ -
<20141017064416.258745A0198@???> sounded
convincing to me.

Also I wonder whether exim shouldn't use the TLS library's
sane default values (I do not know about OpenSSL but GnuTLS default
priorities are supposed to be sane. :-)

Somehow related: GnuTLS will probably drop SSL 3.0 from the default
priority strings.
