Hi,

I found out that I cannot do the SASL smtp auth to the SMTP of my ISP. My
ISP is using M$ exchange server.

I do a testing by telnet smtp.icare.com.hk 25 (my isp's smtp server) (List
1). Note that there are 2 "AUTH" and the "250-smtpi01.icare.priv Hello" is
not the server name i am telneting to. I do further test and able to send a
email through the telnet session.

List 2 is my maillog. You can see the warnings "offered AUTH option
multiple times". Moreover, the SASL framework seems able to 'detect'
"LOGIN" mechanism, and sustainly warned "SASL authentication failure: No
worthy mechs found". Finally, no auth is done and give me error "cannot
SASL authenticate to server smtp.icare.com.hk[203.78.64.145]: no
mechanism available)"

List 3 is the postconf -n

Thanks and Regards,
Alex Kwan
