saya punya problem sama imel and jaringan neh. saya harap teme-temen di milis ini ada 
yang bisa bantu.

ceritanya gini (once upon the time...)
komputer gue terhubung ke jaringan. total komputer 12 biji, pake 2 hub 8 port
os-nya sendiri cuma pake lan biasa (bintang), so ngga pake  NT ato sebangsanya, hanya 
windows 98 di masing-masing kompyut

untuk sharing koneksi ke internet, gue pake wingate 3 titik sekian, 3 berapa gue lupa 
dah..
selama ini cara kaya gini lancar-lancar aja, sampai suatu kita mr.bug mulai dateng. 
ngga serem-serem amat seh, tapi rasanya udah mulai menggangu

masalahnya, untuk kirim imel dari komputer klient (wingate client), pasti ngga mau . 
kalo nerima imel sih lancar. padahal firewall udah dipasang. contoh errornya kaya gini
