Configuring Mac OsX Mail application for use with Joomlapolis hosting for receiving and sending email securely Print

  • 0

Yes, you can read your e-mail from the Apple Mail application on your Mac OsX, as long as it is compliant with the protocols we are using.

To read your mailboxes, you can use either PoP3 with SSL and password authentication or IMAP with SSL. To send e-mails, your agent has to be configured to use SMTP with SSL and password authentication. As a general rule, we always use secured connections. The parameters to configure your mail agent are described below. We will use John Doe and as fictive user and domain.

  • Open Apple "Mail" application, choose Mail -> Preferences -> Accounts, then bottom left press the "+" button to add account, then choose:
  • Account Type: POP or IMAP depending on your preference where mailbox should remain stored: POP on your PC, IMAP: on the server.

  • Description and Full Name: as you choose

  • Email Address:

  • Press "Continue"
  • Incoming server: mail.yourdomain.tld (e.g.

  • Username: (e.g.)

  • Password: your password

  • Press "Continue" and wait for timeout for the check, then press "Continue" again

  • Incoming Mail Security: Tick the checkbox: "Use Secure Sockets Layer (SSL)"

  • Authentication: "Password"

  • Press "Continue"

  • Outgoing Mail Server: mail.yourdomain.tld (e.g.

  • Checkmark "Use Authentication", enter same username and password as in the Incoming email.

  • Press "Continue" and wait for timeout for the check, then press "Continue" again

  • Outgoing Mail Security: Tick the checkbox: "Use Secure Sockets Layer (SSL)"

  • Authentication: "Password"

  • Click "Continue"

  • Review settings and click Done.

On first check mail and send mail you will need to accept the server certificate.

If reading email doesn't work, check that in Advanced tab you have port 995 for POP3S or 993 for IMAPS and in both cases "Use SSL" ticked. If it still doesn't work, wait an hour or change your Mac's IP address if you can (in case wrong port number usage blocked your IP address and you can't access the whole server anymore, e.g. your web-page).

Changing outgoing server later:

You may at a later stage want to change the outgoing SMTP server for your existing account to use our secure SMTP server. To do this, open Apple "Mail" application, choose Mail -> Preferences -> Accounts, and select account in the list, then in the "Account Information" tab, choose "Outgoing Mail Server (SMTP) from the drop-down list, and click "Server Settings..." button below (OR: choose "Add Server..." in the drop-down list), then configure as follows:

  • Outgoing Mail Server: mail.yourdomain.tld (

  • Server Port: leave 25 (alternate port 10025 with TLS/SSL only in case your ISP blocks port 25)

  • IMPORTANT: tick on "Use Secure Sockets Layer (SSL), and Authentication: Password

  • Enter as User Name: yourname@yourdomain.tld ( and your password

  • Click OK and make sure the correct server is selected.

On first send you will need to accept the server certificate.

It is important that you activate the SSL (encryption). If you don't do it, you will not be able to read your mails, and our security system will block your IP address for one hour.


Note: a few ISPs do not allow outgoing SMTP port 25. In that case, you can either call them to open you that port or to tell you which of their SMTP servers to use.

This error is typical of that:

"The connection to the server "" on port 25 timed out", means your Mac can't reach (e.g. due to a firewall) your server on that port.

To check: open a Terminal window (in Applications/Utilities osX has a on the mac and type this command:

telnet 25

You should get a result like this:

Connected to mail.
Escape character is '^]'.

You can then type a HELO command for instance and get result like this:


If you can't reach, it's your firewall, or ISP's firewall.
