Any ideas on how to resolve this? use php as an apache module - thereby the startup delay is only noticed when the webserver starts - this assumes that the problem is a startup problem ... what you describe could be down to a dns configuration error - i.e. the imap extension is trying to resolve some domainname and having a hard time of it.... I can't remember the specifics of such issues but I know that the archives of this list will turn up more info regarding dns config problems (that cause slow downs) > > Thanks, > Edward >
