Email Configuration Based on 20i Mail Servers

Configuring email client program to send and receive emails.

Email may be either POP or IMAP.

Often IMAP is chosen for mobile devices and POP for desktop computers. although there is a tendency to automatically create an IMAP based account.

In the example below I’ve used the domain example.com and the mailbox account info.

Where the option of either a secure or non-secure connection is given it is general better to opt for secure.

Incoming Server Settings

Incoming Email (POP)

Server name: mail.example.com
User name: info@example.com
Connection NO security: Port 143
Connection with security: SSL/TLS with Port 995
Authentication method: normal password

Incoming Email (IMAP)

Server name: imap.example.com
User name: info@example.com
Connection NO security: Port 143
Connection with security: SSL/TLS with Port 993
Authentication method: normal password

Outgoing Server Settings

Outgoing Email (POP)

Server name: smtp.example.com (may be mail.example.com)
User name: info@example.com
Connection NO security: Port 25 or 587
Connection with security: STARTTLS with Port 995
Authentication required: yes
Authentication method: normal password

Outgoing Email (IMAP)

Server name: smtp.example.com (may be mail.example.com)
User name: info@example.com
Connection NO security: Port 143
Connection with security: SSL/TLS with Port 465
Authentication required: yes
Authentication method: normal password

When travelling I’ve found port 25 to be the least successful for the sending of emails. Too often it has been blocked by the property’s internet service provider for the sending of spam emails by some of those partaking of the offered service.

The email client program may show an alert giving a mismatch between the domain (example.com) and the mail server domain. You can accept the difference, giving it an exception.

Alternatively to avoid an issue with the server certificate mismatch use the domain stackmail.com.
