Attachments: saved file from ethereal capture of mozilla <-> hotsmtpd

Description phoenixjim 2004-03-09 16:16:38 UTC 
Version:            (using KDE KDE 3.2.0)
Installed from:    Gentoo Packages
OS:          Linux

I have hotwayd/hotsmtpd setup on my machine for accessing hotmail messages through a standard pop3 client (they are at version 0.8).

I have tested by first connecting via telnet to each port (110 and 25) at localhost (127.0.0.1) and when that succeeded I used mozilla mail to send and receive a short test message. Worked flawlessly.

Kmail receives fine using localhost and 110 with pop3, and sends fine using all external (to me) mail servers. Using localhost (or 127.0.0.1), however, fails with the following message:
Sending failed:
Connection to host 127.0.0.1 is broken
The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.
The following transport protocol was used:
Phoenixjim@hotmail

In previous versions of kmail (3.1.3 specifically) it would send but would mess up the 'to' address by adding an extra '<' at the beginning, causing a failure message from hotmail, and bouncing the original.

Only hotsmtpd is reported as listening to this port (25) in netstat, and using a different port does not change the outcome.

I can repeatedly send using all these settings in mozilla mail, and messages go through as they should, but kmail can't access any port on localhost (or explicitly specified 127.0.0.1, or my router-assigned address) for smtp.

KDE 3.2.0 installed on Gentoo Linux.
Comment 1 Ingo Klöcker 2004-03-10 10:40:40 UTC 
Please listen to the SMTP communication between KMail and hotsmtpd with a tool like ethereal.
Comment 2 phoenixjim 2004-03-10 17:32:11 UTC 
I am inexperienced with such things as ethereal, however I have done as you ask. For security reasons, I have changed the password in kmail and mozilla to an invalid one - kmail never got far enough to complain while mozilla requested the correct password before I cancelled.

I started ethereal, started the capture on all devices, sent the email to myself, then ended capture.

Here is KMail's output in ethereal, as it would be printed to a text file:

Apparently hotsmtpd didn't respond to KMail's "AUTH PLAIN" command. That's a bug in hotsmtpd.

Anyway, do you really need to authenticate to hotsmtpd? Try if disabling "Server requires authentication" in the settings of the SMTP server helps.

If this doesn't help then an ethereal log of the communication of Mozilla with hotsmtpd would be nice. Please attach the log to the bug report instead of pasting it.

Created attachment 5134 [details]
saved file from ethereal capture of mozilla <-> hotsmtpd

I used wrong password deliberately, but as you can see hotsmtpd received
requests properly. Authentication (plain) is required, and only seems to fail
with kmail 3.2.0. Authentication in 3.1.3 worked, but produced flawed "to"
header instead. Authentication by kmail 3.2.0 to non-localhost servers works as
expected.
Comment 5 kingjoe 2004-04-19 22:51:24 UTC 
I am also encountering this bug using the latest hotsmtpd release (.8-1) as of 4/20/04 and running Mandrake 10 Community (kmail 1.6.1).  My instincts are telling me phoenixjim is probably right and the bug is in kmail.  A shame really as kde and it apps are peerless in my humble opinion.
Comment 6 Christopher Cimiluca 2004-04-25 23:15:33 UTC 
I am using kmail 3.2.2 and the problem still exists.  MozillaThunderbird works fine (though I greatly prefer kMail).  I suspect that kMail is doin't something very slightly strange and hotsmtpd closes the connection as a result.
Comment 7 Eric T. Schaffner 2004-05-28 23:41:07 UTC 
This definitely looks like a KMail bug.  Here's more info from the hotwayd forum:

Kmail and Hotsmtpd - the problem = <  
2004-05-22 08:04
When testing hotsmtpd hotmail returns Delivery Status Notification (Failure). In the message it shows the attempted address. The attempted address seems to have too many enclosing angle brackets. The message says:

"This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

<<receiver@example.com>";

Though the original message that is printed below this does not have the extra bracket:

"From: A Sender <sender@hotmail.com>
To: <receiver@example.com>
Subject: ..."

Thoughts?

Comment 8 Christopher Cimiluca 2004-06-03 05:45:16 UTC 
I am using kmail 1.6.2 (not 3.2.2 of course)  the following link to the hotwayd forms details the problem: http://sourceforge.net/forum/forum.php?thread_id=1031389&forum_id=80217  It looks like the problem is with all mail to localhost, not just hotwaysmtp.  So this bug could potentially affect more than the mere hundreds of people who use hotsmtp.
Comment 9 Rich Gilson 2004-07-10 13:39:14 UTC 
I'm having this problem too.  I'm running Kmail 3.2.1 on Suse 9.1.  Kmail fails to send out email destined for Hotmail; however, Evolution works perfectly.  I don't really care for Evolution myself (too much like a M$ product I've worked with) and would much rather use Kmail, but I need this functionality.

I'm getting the same outcome that is detailed in the original bug report here.
Comment 10 Michael Leupold 2008-11-09 23:01:13 UTC 
The release note of the latest hotsmtpd indicates the problems with kmail had been fixed. Unfortunately it's not possible to test this any longer as hotmail doesn't offer free accounts syncable with hotwayd/hotsmtpd any longer. Did this problem go away with the latest release of hotsmtpd somewhen back in 2005?
Comment 11 Christophe Marin 2009-08-23 22:32:59 UTC 
No feedback since November, Changing the bug status.
Comment 12 Torgny Nyblom 2009-11-09 20:45:39 UTC 
No real feedback since mid 2004, closing.
