if you are using tmo in USA, then the outbound messages for email can be rather tempermental. so in order to have it work consistantly, you would have to log into your tmo accout and set up the email on the network server and just use those settingas for yuoufr outbound. ie: outbound: myemail.t-mobile.com login: 8885551212 password: password however, with the smtp.MOBILE.mail. yahoo.com i have not had to use the smtp outbound settings. this was not lways the case when using my 9500 ON S80 and only started when i got my s60 e90.
