Dear S Karthikeyan ,
thank you very much, but i really do not know how to do that because the
paths the mailfolders of the users of my system are in a different server,
and of course spam and nospam have to be users of my system on the same
domain of the others..
Internet ---- Router ------ SMTP with openprotect ---- IMAP server
So how can i manage sa-learn script to find those mails? All the mail is
forwarded using qmail control file smtproutes: mydomain:ipofimapserver.
How can i manage?
