| 107 | <para>If you choose to link <application>Mutt</application> against |
| 108 | <ulink url="http://www.gnu.org/software/gnutls/">GnuTLS</ulink>, |
| 109 | you won't have SSL client certificate support. Specifically the |
| 110 | <parameter>ssl_client_cert</parameter> configuration variable is recognized |
| 111 | as invalid. That means you will loose the ability to use |
| 112 | <command>mutt</command> via SMTP over TLS or in the case when |
| 113 | a client certification is required for authentication on an IMAP server. |
| 114 | For these reasons we recommend to link <application>Mutt</application> |
| 115 | against <xref linkend="openssl"/> if you want SSL/TLS support.</para> |
