Email client settings

You can access your S4 hosted mail via webmail by visiting mail.s-4.host or mail.yourdomain.com.

You can also use any desktop, mobile or web based mail client to access your email accounts. Most modern mail clients should be able to autodetect the correct server settings from your email address during setup.

If for some reason that does not work, you use a mail client without autodetect, or you just want to do it manually, the correct settings are below.


Protocol/Method: IMAP
Incoming server: mail.s-4.host
IMAP Port: 993
IMAP Security: SSL or TLS
Username: Your whole email address.
Password: Your mail password.

Outgoing (SMTP) server: mail.s-4.host
SMTP Port: 587
SMTP Security: STARTTLS (select “always” or “required”, if prompted)
SMTP Authentication: Yes, using the same settings as the IMAP account.


Note: The most common reason for not being able to log in is that you are not using your whole email address in the username field. Please make sure you are doing this before contacting support.

We very strongly recommend using IMAP mail but if you want to access your mail via POP instead then you can do that. Choose POP as the protocol, port 995, and SSL or TLS security in your mail client. The SMTP settings and usernames and passwords all remain the same. 

Alternative SMTP options

We install a plugin by default so that transactional mails from your WordPress site are sent by SMTP via your mailserver. If you are using Gsuite or another external mail provider and want to set up your email to send via that SMTP server then contact us and we can help you set that up.

If you are going to be sending a high volume of transactional mails, newsletters, etc. from your site then you may consider using an external mail delivery service instead of using your own SMTP settings.

Finally, if you want to then you can use your Internet Service Provider’s SMTP instead of ours. If you want to do this then you should disable SMTP authentication and follow instructions from your ISP.
