This is a major problem for users of dialup on an auto basis because its frozen for much of the time it takes the much slower modem communications to complete, compared to a dsl circuit where one can have fetchmail doing the sucking, and handing it off to procmail for treatment by spamassassin and its ilk before finally storing the incoming mail in /var/spool/mail/gene. kmail sees none of that background activity at all. They actually run asynchronously here. kmail then picks that up and sorts it to the correct kmail folder and this does cause the lag/freeze while its doing that. This latter lag/freeze is all I see, but for those that are using kmail to directly access their ISP's mailserver(s), this lag/freeze isn't a 1 second freeze, but a 10-30 second freeze, and that is truly a cast iron bitch version of a PITA. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
