Sending via smtp fails after some time

[Barry Kaplan <gr...@memelet.com>]

I am sending emails from a server. The emails get sent fine for some hours
(up to 24) but then I start getting exceptions that are ultimately:

  Caused by: javax.mail.AuthenticationFailedException: null

I am using the default javaMailSender and sending via gmail. The jvm is
started with Dmail.smtp.starttls.enable=true.

Any ideas what would cause gmail to accept the messages and then decide
later to reject the auth?

(camel 2.5.0)

thanks!

I'm only using one smtp endpoint. I also send email via logback via the same
smtp server with the same credentials and that never fails. I was looking at
how logback uses javamail vs spring and its quite different. Logback sets up
an authenticator with the transport, where passes the u/p with each connect.
Its amazing how (needlessly?) complex the javamail api is. I think if I
didn't have camel to send the emails I would just read the log file and send
paper mails via USPS ;-)

I'm upgrading to 2.7 now, but from what the camel code does I'm guessing the
issue is at the spring layer. But who knows. If I figure it out I'll of
course post it back here.

thanks Claus.

Hi

No idea. You can try upgrading the Java Mail API you use. However I
think some of the latest releases requires JDK6 now.

Also we fixed an issue when you had multiple smtp endpoints defined,
where camel-mail would use the default mail session.
In Camel 2.7 it always uses a new mail session instead. Maybe check
out the source code changes and backport that fix to 2.5 in case you
use multiple smtp endpoints.
