Re: SMTP troubles (AGAIN!) -- RESOLVED!

["James H H Lampert" <jamesl@xxxxxxxxxxx>]

I never did get around to telling the list how I resolved 
the SMTP problems.

First, the "AS/400-native" applications. The problem was 
that the 400 couldn't do domain-name resolutions. It 
turned out that was a firewall problem; when the port the 
400 was trying to use for DNS resolutions (evidently not 
what the WinDoze boxes are using) was opened up, we could 
immediately start sending email through the native SMTP.

Then there's the JavaMail application. As it turned out, I 
was making a wrong assumption: I'd forgotten that I'd made 
a jar, and (seeing the classes just sitting in an IFS 
directory) thought it was running from loose class files. 
THAT's why nothing I did was having any effect. Once I 
started making jars with each test revision, the 
exceptions started to change, and when I got it 
identifying itself properly to the server (I didn't know 
you had to set another property to have it do that!), it 
started working.

As to the bounce messages involving the native SMTP, they 
turned out to be red herrings, evidently from some native 
application test I'd forgotten about.

Thanks to everybody who helped with this.
