Topic: Can not authenicate with ISP's SMTP server

[garyb43]

This particular issue is with 7.3 and the latest revisions via yum update.  I am trying to send email via ISP's server.  I have reviewed bug# 897 and applied that advice.  I am receiving 535 Authentication failure from ISP's server.  I can successfully send mail directly from Thunderbird to the same server on port 465 using the same userid/password that I have entered via the server-manager to e-mail settings.
 
Here is a piece of my smtp-auth-proxy log with debug enabled:

I have searched the forums and bug tracker.  I did find some old reference to SMEServer does not do CRAM-MD5, but that was in 2006.  What am I overlooking and/or doing wrong?

SMEServer is a great distro.  I have used if for years at multiple sites.  I have always been able to figure things out from the either the docs, the code or consulting the info/advice from the wonderful community at contribs.org. 

But, now I am stuck.  Help most appreciated.  Thanks.

Are you sure you have your settings correct?

This looks wrong, as if you are trying to log in anonymously.  Show the output of:

config show smtp-auth-proxy

and

config show SMTPSmartHost

Note: "*****" out your username and password.

Thanks for your prompt response.

Here is what those settings look like ...

[root@pylon2 log]# config show SMTPSmartHost
SMTPSmartHost=fmailhost.isp.att.net

[root@pylon2 log]# config show smtp-auth-proxy
smtp-auth-proxy=service
   Debug=enabled
   Passwd=*********
   PeerPort=465
   Userid=***************
   status=enabled


Thanks for reviewing it.

I'm sorry, I misspoke here.  That is the remote mail server asking SME for your login information/type.  Your server responds back with:

2008-09-07 12:02:57.296280500 Net::SMTP::SSL=GLOB(0x9002228)>>> AUTH CRAM-MD5

It looks like SME supports CRAM-MD5 but for some reason the remote server is rejecting your login.

You should open a bug and report this.

The problem is clearly with att.net's mail server. It advertises that it is capable of CRAM::MD5, but it lies. Others have discovered this as well:
