Hi,
While tracing an SMTP traffic whcih uses AUTH LOGIN, I found that the SMTP decoder do not show the user name and password. See the example: 

18:55:38.674928 aa.bb.200.154 -> cc.dd.238.20 SMTP Command: AUTH LOGIN
18:55:38.674928 cc.dd.238.20 -> aa.bb.200.154 SMTP Response: 334 VXNlcm5hbWU6 18:55:39.494928 cc.dd.238.20 -> aa.bb.200.154 SMTP Response: 334 UGFzc3dvcmQ6 18:55:40.274928 cc.dd.238.20 -> aa.bb.200.154 SMTP Response: 235 2.7.0 LOGIN authentication successful 


But when I used tcpflow, I got this trace,

To mailserver:

EHLO smtp037.mail.yahoo.com
AUTH LOGIN
erRtaW4=
yrFzc3dvcmQ=
MAIL FROM:

From Mailserver:
220 tvm -- Server ESMTP
250-tvm
334 VXNlcm5hbWU6
334 UGFzc3dvcmQ6
235 2.7.0 LOGIN authentication successful.


As you can see the username and password are not decoded by tethereal!!
