Thanks Micah,
I try with tcpdump, and this is the result, some servers
(jankymail-a*dreamhost.com) are using auth methods, at the other hand,
other servers (jankymail-m*dreamhost.com) do not use it. When I use
Linux and Thunderbird, the servers has authentication, but with telnet,
or upas not. Why? Why? Why?
look this:

The SMTP server doesn't claim to support AUTH. You should get a line like this:
250 AUTH CRAM-MD5 DIGEST-MD5
Or some such.
