But is it not that way that if you send a mail from an IMAP client then the message gets transfered to the SMTP server and then the same sent message is again saved in the IMAP send folder? This results in sending the same data (+/-) twice. Once to the SMTP server for delivery and the second time to the IMAP server for saving it in the send folder (and maybe a third time when downloading the message body in the send folder to be chached by the IMAP client). As far as I understood that BURL thing it helping to only send the data once and the second data transfer is then done with BURL. > Wietse > // Steve -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!
