# External email client cannot connect

IMAP/SMTP is included as standard in every plan; you can connect to mailboxes with a desktop mail program or your phone's own email app. If the program cannot connect, the problem is usually an incorrect server name, port, encryption type or password.

- User using an external program

## External email client cannot connect: what should be done?

IMAP/SMTP is included as standard in every plan; you can connect to mailboxes with a desktop mail program or your phone's own email app. Who can apply this: Administrator; User using an external program. If the program cannot connect, the problem is usually an incorrect server name, port, encryption type or password. Until the program connects, you can continue reading all your emails from the SmartMail web dashboard and mobile app.

## What to do

As the username, enter the mailbox's **full email address** (the part before @ alone is not enough). The administrator sees this as the **Mailbox username** in the mailbox's **Credentials** window 1.

As the password, enter the mailbox password; the administrator sees it with **Show password** or sets a new one 2. Your SmartMail login password does not work here.

Compare the server and ports with the table below; the same information is also written in the **Email program settings** box in the window 3.

Make sure that the **authentication is required** option is on for the outgoing server and that the same username and password as the incoming server are used.

| Setting | Correct value

| Incoming server (IMAP) | **imap.smartmail.com.tr**, port **993**, **SSL/TLS**

| Outgoing server (SMTP) | **mail.smartmail.com.tr**, port **587STARTTLS** (recommended) or **465SSL/TLS**

| Username | Full email address

| Password | Mailbox password

The unencrypted IMAP port 143 is closed; if the program tries 143 or “no encryption”, it cannot connect.
