I don't think there's much you can do, other than perhaps using IMAP rather than POP3 and only downloading headers rather than each entire message. Fetchmail by default simply downloads each message and delivers it to port 25 listener on the local machine. At this point, it goes on to the next message, allowing the rest of the delivery procedure to run "in the background" (exim->procmail->spamassassin, or whatever your setup is). Getmail, I believe, bypasses port 25 and the MDA and delivers messages directly to a mailbox. This could potentially slow things down if it has to wait for spamassassin/sanitizer to do their stuff before delivery. You could get better performance by running spamassassin and your MTA as daemons, but I doubt it would have any impact on your online time which is likely bandwidth-limited rather than cpu-limited. -- Brian Nelson <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
