Ah. Yes! (Drat!). Thanks.

Now, I'm running up against the linking problem that was in the second
half (when I tried SSL/TLS w/o SASL). It appears to be looking for
something it can't find, but I'm not sure what lib dlsym, dlerror,
dlopen and dlclose are in...

gcc -Wmissing-prototypes -Wformat -DUSE_TLS -I/usr/local/include
-DUSE_SASL_AUTH -DDEF_SERVER_SASL_TYPE=\"dovecot\" -DHAS_PCRE -g -O
-I. -I../../include -DLINUX2 -o smtpd smtpd.o smtpd_token.o

Thanks in advance...
