I can receive emails but not send them from my Android phone. I am using Yahoo mail and a Samsung Galaxy Ace.
Incoming Mail (POP3) Server: mail.btinternet.com with Port 110
Outgoing Mail (SMTP) Server: mail.btinternet.com with Port 25
Account Name/Login Name: Your email address
(including the "@btinternet.com" or "@btopenworld.com" part)
Password: Your BT Yahoo! password
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: [imap.mail.yahoo.com] [SSL port 993]
[User name is your whole bt email address. Use your normal account password.]
outgoing SMTP server: [smtp.mail.yahoo.com] [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 recently acquired an Alcatel PIXI UNITE smartphone from TracFone (April 2017). It uses Android 6.0. I use an att.net email address and when I let the regular email app add that email account I could receive email but never send it. My email would always end up either in the Outbox or in Drafts. And I could not send the mail from there either. There is currently some kind of craziness going on with Yahoo ATT mail. But the trouble seems to have been fixed (at least for now) by going into Settings (for the email account) and changing part of the default outgoing SMTP server settings. The default setting was: android.smtp.mail.yahoo.com. What I finally discovered after days of trial and error was simply to delete the "android." from the default and bingo!
Sometimes your app preferences inhibit the default email app functions. This seems quite possible if you've disabled apps recently, or have in the past and there's been a recent update. Try resetting your app preferences.
To reset app preferences:
- Open Settings app.
- Tap Apps.
- Tap More settings (three-dot) icon at the upper right.
- Tap Reset app preferences.
