Problem with getting messages via POP3
Hi!
I use this route:
<route>
<from
uri="pop3://mail:110?password=123456&username=master@mail.example.com&delete=true&debugMode=true"/>
<to uri="wmq:queue:OUT"/>
</route>
Processing is correct if only one message in mailbox. But a lot of messages
(f.e. n = 2) in mailbox cause strange processing:
1. All n messages were processed correctly: n messages appear in WebSphere
queue.
2. One message was deleted from mailbox.
3. After polling timeout go to step #1 with n-1 messages.
And debug log from SUN's Mail framework is:
12/08/01 12:51:13 S: +OK Microsoft Windows POP3 Service Version 1.0
<22...@mail.example.com> ready.
12/08/01 12:51:13 C: USER master@mail.example.com
12/08/01 12:51:13 S: +OK
12/08/01 12:51:13 C: PASS 123456
12/08/01 12:51:13 S: +OK User successfully logged on
12/08/01 12:51:13 C: STAT
12/08/01 12:51:13 S: +OK 2 796
12/08/01 12:51:13 C: TOP 1 0
12/08/01 12:51:13 S: +OK 398 octects
*HEADERS OF THE FIRST MESSAGE*
12/08/01 12:51:13 C: TOP 2 0
12/08/01 12:51:13 S: +OK 398 octects
*HEADERS OF THE SECOND MESSAGE*
12/08/01 12:51:13 C: RETR 1
12/08/01 12:51:13 S: +OK 398 octects
*HEADERS AND BODY OF THE FIRST MESSAGE*
12/08/01 12:51:13 C: RETR 2
12/08/01 12:51:13 S: +OK 398 octects
*HEADERS AND BODY OF THE SECOND MESSAGE*
12/08/01 12:51:13 C: *DELE 1*
12/08/01 12:51:13 S: +OK Message marked as deleted
12/08/01 12:51:13 C: *QUIT*
12/08/01 12:51:13 S: +OK Microsoft Windows POP3 Service Version 1.0
<22...@mail.example.com> signing off.
So we can see that the only the first message had been deleted before
session closed.
What's going on?

Does anybody use MailComponent for obtaining messages via POP3? Or... Does
anybody test Camel-POP3 interaction with more than one message
simultaneously?

Sun mail framework works fine with several mail-msgs are obtained via pop3:
1) read n messages one by one from pop3
2) process n messages
3) mark processed messages for deletion (using pop3 command which is wrapped
by mail framework)
4) close pop3-"transaction"
As a result one iteration yields: n messages were processed and deleted from
mailbox.
But Camel's MailComponent doesn't work as I described above.

Hi
pop3 has limitations with delete/seen flags on processed mail messages.
Use imap instead if possible.
