Thank you for you help Hunter

I'm sure you are right about authentication, but I don't understand how my two computers at home work without me having to think about authentication, but the server located at the ISP is stuck on this. There must be something in the configuration that tells WO where to send.

The default value in each case is SMTPHost = smtp. Somehow WebObjects gets a proper smtp address. Do you know if it uses the email settings in Mail? The Internet System Preference also lists an Outgoing Mail Server, so I guess that's the logical place to set it.

Your "mail.host.com" is a value I haven't tried, or is that specific to your network? I haven't found anywhere that allows me to set user and password inside my program.

I thought it might be a block on port 25 so I fired up Mail on the server via Timbuktu and sent myself a message. That worked fine, and presumably passed out through port 25

I had a similar message. My problem was that my ISP blocks port 25 so I cannot use it to send... When I moved my machine to another network that allowed outbound 25, it was fine.

I set my SMTP host in my Application class:

setSMTPHost("mail.host.com");

Doesn't mac.com require SMTP to be authenticated? I.e. you have to pass user/pass to send via their servers?

I'm having trouble using WOMailDelivery to send email from my WO application.
It works perfectly well on my development Mac in dev mode
I works on my test deployment Mac in deployment mode (this machine also has WO development installed, if that makes a difference)


Move it to the deployment server and when I try to send a mail I get
	java.net.UnknownHostException: mailhost

All computers are Macs running OS X. 10.2.6 (well one has 10.2.8, but that one is OK ) and WebObjects 5.2.1

I thought the problem might be because the server had never been used for email. I fired up Mail (this is a painful process on a remote server through Timbuktu without true broadband at my end) and found that the owner of the server had not set up password authentication on the email accounts. I thought maybe WebObjects would use Mail's smtp configuration, so I corrected the omission but it hasn't helped.

I added a line to the application class
        System.out.println(" SMTPHost = " + this.SMTPHost());

On startup this tells me that the SMTPHost = smtp

I tried adding -WOSMTPHost=smtp.mac.com to the WebObjects instance startup parameters. The change is duly reflected in the println message but I still can't get the mail out. I did manage to get the error message to change to "relaying denied 554 recipient address rejected"
This apparently means that the From address does not match the smtp authentication, except that I think they are the same.


Does anyone have any other clues? Does WebObjects use the mail configuration, or am I wasting time with that line of investigation?
