dovecot - May 2010 - POP3 Problem with SPAM-Mail's over sieve

Hi together,

i am currently using dovecot 1.2.10 with the sieve-plugin and use a 
sieve-filter to sort the SPAM-Mail's directly into a Junk-Folder:

require "fileinto";
# rule:[junkfilter]
if header :contains "X-Spam-Flag" "YES" {
  fileinto "Junk";
}


My problem is now, if i try to retrieve the Mails via POP3, i did not get the 
SPAM-Mail's in the Junk-Folder, only the normal ones, that are not filtered 
over the sieve plugin.

Could anyone tell me how to solve that issue ?

best regards
  Michael

POP3 has no concept of folders, so only mails in INBOX are accessible.

In the wiki there's a "Virtual INBOX por POP with all folders"  
solution, but the net effect is displaying all e-mails from all  
folders in the INBOX, so you might save a few processor cycles and  
simply not filter mails in folders in the first place.

Some assembly required.

Hello Michael,

I don't know if there are any other new ways of doing this, but a while 
ago i had that same need. I solved it by creating a wrapper and using

NOTE: This is for maildir only

mail_executable = /usr/local/bin/pop-wrapper.sh

That wrapper basically copies all the messages from the Spam maildir 
into the Inbox maildir, executing /usr/lib/dovecot/pop3 afterwards.

a simplistic approach would be something like

#!/bin/sh
for i in `/usr/bin/find Maildir/.Spam -type f -iregex ".*/new/.*" -o 
-iregex ".*/cur/.*"` ; do mv $i Maildir/new/ ; done
exec /usr/lib/dovecot/pop3
