Hi Danny,

I've totally found James/SMTP-AUTH to be totally rocking too, but this problem I had with the lan at work made it appear that when I telneted to james and issued the ehlo, that no AUTH LOGIN PLAIN was returned.

I downloaded Ethereal on my workstation and fired up ngrep on the james box so that I could sniff the network locally on both machines. In the ngrep on the mail server I could see James responding with the AUTH LOGIN PLAIN but in the sniff from my local workstation there was no such thing.

The firewall was stripping it out, presumably so that it could proxy the connections to mail servers and handle any SMTP-AUTH automatically. Very weird.

Many firewalls handle SMTP differently than other connections.

Usually they simply filter packets based on their source and destination. It is often possible, however, for firewalls to be setup to proxy SMTP traffic on port 25.
This allows the firewall to use services such as RBL's (Relay Black Lists) to block mail from known open relays, and possibly implement other rules.


I don't think this is your issue though.

When you connect from anywhere and issue EHLO you should get "250 AUTH LOGIN PLAIN"

but you are only required to actually authenticate yourself if the "RCPT TO" recipients are not local.

I've found SMTP AUTH to be quite effective and stable, but I'm using James from cvs, and the first release of v2.1 not the latest release of v2.

Subject: SMTP AUTH scares me...


Hello guys,


I have troubles with the smtp protocol enabled with auth and verification. When I send mails from my lan, there are no problems, the log shows correctly that the auth mechanism works well. When I try the same from the internet, the auth fails. When I try to telnet my james server and issue a ehlo command, I must retry several times before getting the message "auth=auth login"...

Between my james server and the Internet, I have a Dlink DI804 router/firewall. Does it possible that it's the problem? How can I solve this?

Any idea? Thanks a lot,
Emmanuel
