Outgoing e-mail SMTP on iphone not working?

Hi Guys,

I have a problem when i use webclient for my e-mail it works i can send and receive e-mails.
Now when i configure this client to my iphone with my settings:

Username: info@myble.nl
Password: Use the email account’s password.
Incoming Server: mail.myble.nl
IMAP Port: 143
POP3 Port: 110
Outgoing Server: mail.myble.nl
SMTP Port: 25
Authentication is required for IMAP, POP3, and SMTP.

i can receive e-mails.. but i can not send.. it says "Saving message in outgoing"can not send message?

I checked my server in WHM.. how can i fix this please?

Thanks!
