I can receive emails but not send them from my Android phone. I am using Yahoo mail and a Samsung Galaxy Ace.

Are you using the stock email client or another client? What are the settings that you are using (ex. Imap, POP, servers and ports)? – Brad Aug 13 '12 at 12:18
Outgoing: SMTP:, Port:587, Security type:None. – Bonzo Aug 13 '12 at 12:22
You're using the Yahoo! Mail app, correct, and not the stock email app? – Al E. Aug 13 '12 at 12:39
No i am using the pre-installed email app. My email is run by yahoo but my email is and the server is – Bonzo Aug 13 '12 at 12:40

Note that SMTP Authentication needs to be enabled. – w3dk Aug 13 '12 at 15:01

I have been experiencing the same problem with a Samsung Galaxy S2 and a BT yahoo account, namely can receive but not send email. After many unsuccessful variations on POP3/IMAP and port combinations the following finally seems to have worked:

incoming IMAP server: [] [SSL port 993]
[User name is your whole bt email address. Use your normal account password.]

outgoing SMTP server: [] [SSL port 465]
(Finally - and crucially - select "require sign in" and use your email address (username) and account password as for the incoming.)

This may only be relevant to the Galaxy S2

I don't have the ability to set IMAP, I can only use POP3. I also tried setting outgowing mail server and I just get an error... – Bonzo Aug 13 '12 at 12:30

I had tried all combinations of security settings but crucially it was the 'request sign in' bit that was needed along with selecting port 465 (SS L certificates option).

I had changed my password online with Yahoo and that was the issue. As soon as I entered my new password, my outgoing messages worked just fine.
