Answer 2

you can manage relay host for yahoo, gmail, hotmail etc. in this way-
NSArray *arr1 = [fromEmail componentsSeparatedByString:#"#"];
NSArray *arr2 = [[arr1 objectAtIndex:1] componentsSeparatedByString:#"."];
if ([arr2 containsObject:#"gmail"]) {
smtp_message.relayHost = #"smtp.gmail.com";
}
else if ([arr2 containsObject:#"yahoo"]) {
smtp_message.relayHost = #"smtp.mail.yahoo.com";
}
else if ([arr2 containsObject:#"hotmail"] || [arr2 containsObject:#"live"]) {
smtp_message.relayHost = #"smtp.live.com";
}
else
{
NSString *smtpRelay = [[NSString alloc]init];
smtpRelay = [NSString stringWithFormat:#"smtp.%#.com",[arr2 objectAtIndex:0]];
smtp_message.relayHost = smtpRelay;
}
