How to authenticate Gmail with openssl s_client? [closed]

up vote 1 down vote favorite

I use the following commend to access my gmail account in telnet:

openssl s_client -starttls smtp -crlf -connect smtp.gmail.com:25

then I login and receive an error:

auth login
334 VXNlcm5hbWU6
user "some base64"
334 UGFzc3dvcmQ6
pass "some base64"
535-5.7.1 Username and Password not accepted.

I'm sure my user name and password are correct. Is there something I'm missing?

Can you also try using SWAKS? jetmore.org/john/code/swaks – adamo Mar 14 '11 at 6:21

Try without the keywords user and pass, for example

auth login
334 VXNlcm5hbWU6
bm90bXlyZWFsdXNlcm5hbWU=
334 UGFzc3dvcmQ6
bm90bXlyZWFscGFzc3dvcmQ=
235 2.7.0 Accepted

Actually, VXNlcm5hbWU6 is Username: and UGFzc3dvcmQ6 is Password:, so no need to define your input.
