Email Channel

Connect mailbox via IMAP/SMTP

Updated 2026-09-09

Go to Settings -> Email channel and choose the manual IMAP/SMTP option when your provider is not Google or Microsoft.

You will need, from your mail provider:

  • IMAP host, port and whether TLS is used, plus the user name and password.
  • SMTP host, port, TLS setting, user name and password.

EspressoDesk stores these credentials encrypted and uses them for both directions: reading new mail and sending your replies. Save the form and the connection is tested immediately; any error message from the server is shown so you can correct the port or password.

If your provider requires an app-specific password, generate one there and paste it instead of your normal password.

What you need

Four things from your provider: the incoming server and port, the outgoing server and port, whether encryption is SSL or STARTTLS, and the user name with its password or application password.

Step by step

  1. Open Settings -> Email channel and choose the manual connection.
  2. Fill in the incoming and outgoing details and save.
  3. Send a test message from a private address and confirm the ticket appears.
  4. Reply from EspressoDesk and confirm the answer arrives with your address as the sender.

Common problems

  • Authentication fails: your provider needs an application password, not the normal one.
  • Mail arrives but replies do not leave: the outgoing port or encryption is wrong, or the provider requires authentication on sending.
  • Nothing arrives at all: the incoming server rejects the connection, often because access for external programs is disabled in the mailbox settings.
