Hiya homies,

I've googled and read docs until my eyeballs are falling out, hopefully one of 
you fine chix0rs will know- do I need to enable TLS/SASL in both Postfix and 
Courier? I have it enabled in Courier, and clients are using it like happy 
little clams. However I have not enabled it in Postfix:

$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 windbag.test.net ESMTP Postfix (Libranet/GNU)
EHLO windbag.test.net
250-windbag.test.net
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-XVERP
250 8BITMIME
^]
telnet> quit

Telnet would report

   250-STARTTLS
   250-AUTH LOGIN PLAIN OTP DIGEST-MD5 CRAM-MD5
   250-AUTH=LOGIN PLAIN OTP DIGEST-MD5 CRAM-MD5

when TLS/SASL are enabled in Postfix. It's easy enough to add to Postfix- do I 
need to? I think I don't, but I'd like to hear from wiser heads.

thanks!

PS- OpenSSL has its own encrypted telnet-type client for testing this stuff:

# openssl s_client -connect localhost:995
<boatloads of output, use the standard POP3 telnet commands>
