So there are more problems than just sendmail... Try to
reinstall OpenSSL (system version).

Oh - it seems you want SASL. You want SASL? It's complicated,
but possible with system sendmail.

1. Install cyrus-sasl and cyrus-sasl-saslauthd (version 2) from
   ports or pkg. Default configuration is okay.

2. Add to /etc/make.conf:

	SENDMAIL_CFLAGS=-I/usr/local/include -DSASL=2
	SENDMAIL_LDADD=/usr/local/lib/libsasl2.so

   Note that the Handbook at 30.9 # 4 is _wrong_; this works.
   https://docs.freebsd.org/en/books/handbook/mail/#SMTP-Aut

3. Recompile system sendmail:

	# cd /usr/src/lib/libsm
	# make
	# cd /usr/src/lib/libsmutil
	# make
	# cd /usr/src/usr.sbin/sendmail
	# make
	# make install

4. Check: Now you have SASL2 support

	# sendmail -d0.1 -bt < /dev/null

   Now SASLv2 will be listed.

If you actually need SASL to authenticate, start and configure
the service accordingly.

I'd say you find them in the program's Makefile.

Yes, that is a trend now...




Good luck!





Oh, one further thing to check: Your sendmail configuration.
If your control file has

	define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN
 PLAIN')dnl

then maybe just remove the one that requires SASL, if you
do not need it.
