The squeaksource.com image runs on dan.box.squeak.org, and it occasionally tries to send SMTP mail to mail.squeak.org, which resolves to 162.242.237.43. The attempt to connect to the mail server results in a 503 service not available error. This in turn results in failures that hang the squeaksource image (but that is a subject for another discussion). For now, I am trying to understand how to get mail delivery working.
I need some help to understand the source of the error. Is there something about our Rackspace server configuration (and network configurations) that would prevent mail delivery from working when the SMTP client connects from a Squeak image running on dan.box.squeak.org to the mail server at address 162.242.237.43?
Background: For purposes of debugging, I am VNC connecting to a modified squeaksource.com image running on dan.box.squeak.org, and I am evaluating the following snippet to debug the SMTP connection issue:
fromAddress := 'squeaksource@source.squeakfoundation.org'. recipientList := OrderedCollection new add: 'box-admins@lists.squeakfoundation.org'; yourself. recipientList := OrderedCollection new add: 'dtlewis290@gmail.com'; yourself. messageText := 'This is a test message from a squeaksource.com test image.'. smtpServer := 'mail.squeak.org'.
SMTPClient deliverMailFrom: fromAddress to: recipientList text: messageText usingServer: smtpServer.
The connection failure results in an error response '503 5.5.1 Error: send HELO/EHLO first'.
Help and pointers appreciated.

I am only guessing, but stepping through the smtp interaction in a debugger tells me that an optional username/password may be exchanged in the smtp protocol. The squeaksource.com image does not supply this, possibly because it originally sent mail via box2.squeak.org, and now via mail.squeak.org (???).
Is a username/password required for the client on dan.box.squeak.org to connect to the smtp server at mail.squeak.org?

Sorry I did not step in earlier.
Yes. I configured the mailer to _relay_ for our boxen, so that there's no user/pw interchange. What would it be in the first place?
Also, You could try localhost, there's an exim running that uses mail. as a smarthost.
I wonder, because it had worked up until now…
Best regards -Tobias

I was just taking a wild guess there, thanks for the clarification.

Well d'oh! I am an idiot. I thought I had tried that a long time ago, but apparently not. I just ran a test with localhost and it works fine.

It has never worked since the move to Rackspace. I had disabled the mail delivery in the squeaksource.com image to prevent problems (VMMaker is on source.squeak.org now, and I'm not sure that anyone would care about the mail notifications anyway).
But it turns out that there are occasional error conditions in SqueakSource for which the image tries to send mail to the box-admins list, which (due to the mail failures) results in a recursive error condition that eventually locks up the image.
I'll update the squeaksource.com image to relay the mail via localhost. That will resolve the problem of occasional image lockups.
Thank you!
Dave
