bug for RemoteDelivery + suck it and see workaround
Hi All
I noticed a few problems recently with outgoing mail on James 2.0a2, one of
which was repeatable :-\ Every time I tried to send an email to an address
at a specific host James threw an Unknown SMTP host exception, which it
reported in James.Mailet.log, see below...
I couldnt see any logical reason why, so almost on a whim I commented out
the line in the transport mailet RemoteDelivery.java which sets the mail
session property "mail.smtp.timeout", on line 382. I figured it couldnt do
any harm as the default is apparently an infinite timeout.
with the timout property commented out the mail goes through just fine.
It wouldnt suprise me if this was due to a bug in Sun's Java mail api.
Kevin.
P.S. the smtp host happens to be an M$ exchange server if thats relevant.
Microsoft ESMTP MAIL Service, Version: 5.0.2195.2966.
note that the james tries to deliver this message forever, always
getting the same exception

hmm, I dont think making the timeout longer will make a difference, isnt it
set at 10 minutes ? the problem smtp host takes less than 30 seconds to
throw an Unknown SMTP Host exception. Perhaps trawling through the JavaMail
source is the best option ?

Re: bug for RemoteDelivery + suck it and see workaround

Kevin,
That does rather suck. I've been seriously considering writing my own SMTP
delivery part and removing the use of JavaMail for the remote delivery. I
had added the timeout because what was happening was sometimes you would not
get a disconnect recognized, so the delivery thread would basically never
recover. After a while, all of the remote delivery threads get stuck like
this, and you have no more delivery.
Thanks for the report. Maybe we can make the timeout significantly long, or
perhaps look into the JavaMail code to see why it's doing this.
