ull always have trouble with this if you dont have a good smpt, anyway, you can use the gmail SMPT, you can just sign in in gmail if you dont have an account already, then sign in, go settings, then forwarding and POP/IMAP, then Enable POP for all mail (even mail that's already been downloaded), then ENJOY :
smpt host: ssl://smtp.gmail.com
smpt user: ur gmail user
smpt pass: ur gmail pass
smpt port: 465
good luck, rep++ if i did help, if i helpt and u dun rep ill find u in rl and rape u (lol jk)
