I don't know off hand exactly how QMT does authentication with smtproutes.
That being said, 3 common auth methods are plain, login, and cram-md5.
QMT should only use a method that's shown by the receiving server's AUTH
reply to the ehlo command. You can check to see what the receiving
server lists by telnetting to it, and issuing an ehlo command. I would
check this first.
If cram-md5 is listed, that's probably what QMT will try to use first. I
don't know if QMT is programmed to try other methods if the first one
fails or not. From what you said, I'd guess not. It could be either end
of the connection though that's not doing/allowing a 2nd try. The RFC
states pretty clearly that subsequent methods may be tried should the
first one fail.
I don't know of a way to tell smtproutes to which auth method to use. It
should be automatic, based on what the receiving server shows is
available. If you need to use a specific auth method, I think you'll
need to modify the source code. (I needed to do this with the python
smtp module a few months ago, which resulted in an enhancement to that
module. QMT doesn't use that python module though.)
BL, if the smarthost is showing cram-md5 and can't handle it, it should
allow subsequent retries. You need to determine whether it's QMT or the
smarthost that's not doing/allowing retries, and fix accordingly.
Otherwise, you might modify the QMT source to try plain auth first,
which I'm pretty sure will work for you.
Please note, I'm speculating a bit here, but HTH anywise.

Hi Everyone,
Some more details which I got after discussing with my ISP on the below
topic. According to my ISP, the server is sending some kind of encrypted
password for login authentication but it require PLAIN authentication to
connect to SMARTHOST.
I'm not getting where is problem because I'm entering PLAIN password in
SMTPROUTES.
Any help.
Thanks ans regards,
Amit

Hi Everyone,
I'm using smarthost in SMTPROUTES to relay mails from one of my
qmailtoaster server but its giving me error uanle to authenticate
remote server with given username and password. But with same smart
host username and password I'm able to send mail from my Outlook
express.
My SMTPROUTES file looks like
:smart_host_server_ip:25 smarthost_username smarthost_password
