Can't send email
- Check the outgoing (SMTP) server is set to mail.yewho.com.my with authentication enabled — the same username and password as incoming.
- Try port 465 (SSL) or 587 (STARTTLS). Some networks block one or the other.
- Make sure your mailbox isn't full — a full mailbox can stop sending.
Can't receive / login fails
- Confirm your username is your full email address, not just the part before the @.
- Re-type your password carefully — it's case-sensitive.
- Check the incoming server is mail.yewho.com.my on port 993 (IMAP, SSL).
