thanks a lot uTMY that's about all the information i wanted / needed i will work on it asap this problem of blocked port 25 never occurs when going through routers in hotels while traveling much worst - this is default problem for all ppl in the Philippines using the largest mobile phone provider Smart Communications and connecting via 3G to my servers. living and working in paradise means far from hotels and cities on beautiful islands !! to test I have to go out of my current temporary home in a city, as I have at my current place no mobile signal in my room to test 3G mailing until yesterday I had another problem that suddenly disappeared - I never could ping my own localhost or 127.0.0.1 on my N900 - and last night suddenly that started to work after I did a full maemo 5 upgrade hours before ( and multiple reboot of the N900 ). may be part of the problem also was inside my own N900. unfortunately I have the official Philippine version - that usually is weeks or months behind european version of N900
