I've had issues with slow connections in the past where TCPDOPTS, wherever it occurs in your Courier config files, doesn't contain "-noidentlookup", and "-nodnslookup" in the case of systems where reverse resolution of IP addresses isn't available. This may not be your problem, but if you're not sure how TCPDOPTS is set in the esmtpd and imapd config files it might be worth checking. -- Lindsay Haisley | "UNIX is user-friendly, it just FMP Computer Services | chooses its friends." 512-259-1190 | -- Andreas Bogk http://www.fmp.com | ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
