Quick checks for sending and receiving issues.

  1. Check the domain’s MX record — if your mail is with us, it should point to mail.yourdomain.
  2. If the mailbox quota is full, new messages are rejected — delete old messages or increase the quota.
  3. Check the port and encryption in your app settings — see IMAP / SMTP settings.
  4. If your sent message bounces, send support the error text from the bounced message.
  5. Sign in to DenizMail and check: if it works there, the problem is in your device app’s settings.
