What port should I set for my mailbox?
For configuring email in various email clients (Outlook, Thunderbird, Mail, etc.), it is necessary to correctly set the port numbers. These are based on the type of protocols IMAP, POP3, and SMTP, including whether you have chosen an unsecured or secured connection. We strongly recommend using encrypted secure protocols - SSL/TLS and STARTTLS.
Email Protocol Overview
| Protocol | Port | Encryption |
|---|---|---|
| POP3 | 110 | unencrypted |
| POP3s | 995 | SSL/TLS |
| IMAP | 143 | unencrypted or STARTTLS |
| IMAPs | 993 | SSL/TLS |
| SMTP | 25 | unencrypted or STARTTLS |
| SMTP | 587 | unencrypted or STARTTLS |
