Do you mean that the built-in POP3 server is always off by one email?

Hmmm... OK... lets try to figure this one out :)

If you start ZO=CB in debug mode, you can see the entire POP3 session =20=

from the server point of view:

% java -jar Zoe.jar debug

Here is a typical POP3 session between ZO=CB and Apple's Mail.app 1.3.9 =20=

(v619/619.2):

s: +OK Hi
c: USER username
s: +OK
c: PASS password
s: +OK Welcome
c: STAT
s: +OK 1702 6808000
c: UIDL
s: +OK unique-id listing follows
s: 1 36EC2BA80103305A0C1E3F820B6FA4EF
    ...
c: LIST
s: +OK 1702 6808000
s: 1 4000
    ...
c: RETR 1
s: +OK Message follows
    ...

You can do the same by using telnet directly:

% telnet localhost 10110

And then typing the relevant POP3 commands.

The critical information provided by ZO=CB's POP3 server is how many =20
messages there is. This is handled in the SZPOPSession.uuids() method:

http://dev.alt.textdrive.com/file/ZOE/Frameworks/SZPOP/SZPOPSession.java

This method in turn calls SZTimeline.uuidsOfClassInStore() to get a =20
list of message ids:

http://dev.alt.textdrive.com/file/ZOE/Frameworks/SZObject/=20
SZTimeline.java

Which usually calls SZIndex.ids() to get the ids directly from Lucene's =20=

indices themselves:

http://dev.alt.textdrive.com/file/ZOE/Frameworks/SZObject/SZIndex.java

As far as I can tell, I always get up-to-date messages from ZO=CB's POP3 =
=20
server. Could someone try to track down this problem?

Thanks!

Cheers,

R.
