Did you read the fine manual?
http://stunnel.mirt.net/static/stunnel.html

     options = SSL_options

           OpenSSL library options

           The parameter is the OpenSSL option name as described in
           the SSL_CTX_set_options(3ssl) manual, but without
           SSL_OP_ prefix.  Several options can be used to specify
           multiple options.

           For example for compatibility with erroneous Eudora SSL
           implementation the following option can be used:

               options = DONT_INSERT_EMPTY_FRAGMENTS

so the answer is:
options = NO_SSLv2

Best regards,
    Mike
