>From looking at the sendmail makefile, it looks like the ssl and crypto
libraries are now added automatically unless you use the
WITHOUT_OPENSSL build option, it contains this:

    .if ${MK_OPENSSL} != "no"
    # STARTTLS support
    CFLAGS+=    	    -DSTARTTLS -D_FFR_TLS_1
    LIBADD+=    	    ssl crypto
    .endif

I think that means you can now reduce the settings in your make.conf to

    SENDMAIL_CFLAGS= -I/usr/local/include -DSASL=2 -DDNSMAP
    SENDMAIL_LDFLAGS= -L/usr/local/lib
    SENDMAIL_LDADD= -lsasl2

and I think you won't get the LIBADD warning for -lsasl2 because it's
not a standard base library (but I'm not sure of that).
