Hi guys, thanks again for your help with the Ameritrade problem. The issue has now been fixed. It took a couple of weeks, but they got there in the end. To quote: "Last week all filters for international IP addresses have been removed and e-mail traffic should be flowing normally." So the moral is that some big US companies have international IP addresses filtering policies. Something to watch out for. PS: Their mail server is now mx01.ameritrade.com, not smtp.ameritrade.com. jfp. ------------------------------------------------------------------------ Jean-Francois Pirus <jfp(a)clearfield.com> Senior Software Engineer Phone (+64-9) 358 2081 Clearfield Software Ltd Fax (+64-9) 358 2083 4th Floor 8-10 Whitaker Place Mob (+64-21) 640 779 P O Box 2348 Auckland, New Zealand ------------------------------------------------------------------------
