pop3 issue on specific message
I'm having a problem popping mail from james using netscape7.1. It does
fine overall but seems to get hung-up on a specific message. I'm almost
100% sure that its not netscape because I have two mailboxes setup in
netscape, one pulling from my ISP and one from James. I have my ISP set
to forward mail to the James server, the message was retrieved fine from
the ISP but the exact same message seems to have trouble from James.
Below is the details of the pop3 debug output :

Any ideas? Why is James returning "-ERR" after the XSENDER 3, and why
does Netscape issue a UIDL and restart the process after receiving the
first "-ERR"?
Thanks

There are messages, but Netscape isn't asking for them. The "reset()"
message is just a debugging notice in James that it is resetting the
watchdog timer for that connection.

Well, the fact that DELE x works multiple times in a row is bothersome.

I did my test with James v2.2.0a8 using JDBC, but the file system shouldn't
be the issue. The DELETE operation is handled internally. I just checked
the diff between the code I'm running, and v2.1.2, and I don't see anything
that would make a difference.

Can you run the same telnet test I did and check the results?

A quick search on XSENDER showed alot of confusion so I agree that it
isn't involved.
Its true that James doesn't hang, rather it seems to prematurely abort,
possibly because Netscape closes the connection. You can see that there
are 594 messages in the queue, but after 'RETR 3' there is a reset and a
stop. After further research I also realized that it isn't a specific
message. I deleted emails day-by-day until Netscape was able to get
through the remaining messages and pretty much had to delete everything
until it could pop messages successfully. I may try adding back
messages until it gets stuck to see if there is anything specific about
the sequence.
What I don't understand is why Netscape was able to pop the same
messages from my ISP successfully, but gets stuck popping from James.
I'm using James 2.1.2. It may be worth noting that I'm using the
filesystem to store messages not the database.
Thanks

Because XSENDER is not supported. The command itself is not without some
controversy. As far as I know, it is a Netscape-specific command, which
Qpopper (Eudora) and even Netscape recommend turning off.
http://www.eudora.com/qpopper/faq.html#netscape.auth
http://www.geocrawler.com/mail/thread.php3?subject=xsender&list=126
For those who don't know, XSENDER "[gets] the email address of the sender of
the specified message. Client uses this to query whether an individual
message has been authenticated. Server returns an empty OK string if no
authenticated sender is found."
ref: http://developer.netscape.com/docs/manuals/messaging/msdkj/prorj.htm
It would be possible to support it once we have mail attributes.
> why does Netscape issue a UIDL and restart the process
Who knows.
More disturbing is this sequence:
Command received: DELE 1
Sent: +OK Message removed
Command received: DELE 2
Sent: +OK Message removed
Command received: UIDL
Sent: +OK unique-id listing follows
Command received: DELE 1
Sent: +OK Message removed
Command received: DELE 2
Sent: +OK Message removed
Something is wrong with that sequence because the second set of deletes
should have returned an -ERR response saying that the message was deleted.
I just tested this using telnet:
RSET
+OK
LIST
+OK 4 8314
1 3491
2 2911
3 956
4 956
.
DELE 3
+OK Message removed
LIST
+OK 3 7358
1 3491
2 2911
4 956
.
UIDL
+OK unique-id listing follows
1 Mail1057948559166-4377
2 Mail1057948805540-4386
4 Mail1057949404326-4408
.
DELE 3
-ERR Message (3) does not exist.
So that is working as expected. What verson of James are you using?
In any event, I don't see from your log extract where something is getting
hung-up. James doesn't hang. Is Netscape misbehaving?
