Topic # 106293 21-Jul-2012 08:43 Send private message

I'm writing a Spring/Java/Tomcat app, and I'm having a problem with getting it to send email. I can send email fine from a given piece of code when run as a standalone Java application, but when it runs within Tomcat it runs fine but Javamail doesn't work properly, throws an error at the start of the email conversation. I think I may have narrowed it down to multiple javamail implementations, but I'm not sure yet, but I'm still seeing something a bit bizzare.

The most bizarre part is the email server isn't behaving as I'd expect when I telnet to the server (try it youserlf) - the first EHLO or HELO is always sent a 500 unrecognised command reply, but exactly the same command repeated works.

220-gator84.hostgator.com ESMTP Exim 4.77 #2 Fri, 20 Jul 2012 15:18:52 -0500
220-We do not authorize the use of this system to transport unsolicited,
220 and/or bulk e-mail.
EHLO testdomain.com
500 unrecognized command
EHLO testdomain.com
250-gator84.hostgator.com Hello testdomain.com [my IP removed]
250-SIZE 52428800
250-PIPELINING
250-AUTH PLAIN LOGIN
250-STARTTLS
250 HELP

And another session

220-gator84.hostgator.com ESMTP Exim 4.77 #2 Fri, 20 Jul 2012 15:20:10 -0500
220-We do not authorize the use of this system to transport unsolicited,

HELO bob.com
500 unrecognized command
HELO bob.com
250 gator84.hostgator.com Hello bob.com [my IP removed]

Here's the logs from tomcat which show much the same thing

DEBUG: getProvider() returning provider protocol=smtp; type=javax.mail.Provider$Type@62e26a4a;.apache.geronimo.javamail.transport.smtp.SMTPTransport; vendor=Apache Software Foundation;version=1.0

EHLO (removed)

HELO (removed)
220 and/or bulk e-mail.



The thing that throws me is telnetting to the SMTP port gives me the same failure as Javamail gets running inside tomcat, but running as an app it works fine.

I know a little about email, I wrote an email server about ten years ago, nothing commercial just a university project, but I'm not an email expert. Any thoughts or ideas?

Any difference if you use the ip address of the mail server?

Nope. I discovered that if you use telnet connection type this happens, if you use a raw connection type (in putty) the problem goes away.

I also tracked down the Java problem. EclipseLink depends on a library that depends on another JavaMail implementation, so I need to get JavaMail onto the Tomcat classpath before that. It's proving to be weird though, class loading inside tomcat's a pita.
