CFTS e-mail Ports and Services Open


To access your hosting account mailboxes on our servers with an email client such as Outlook, iPhone, MacMail, or another client of your choice (either POP or IMAP with SMTP for sending mail), you have to configure it. You'll find the required configuration information/settings below: Ports in use for secure and non-secure protocols, excluding any custom ports that may be set up for you.

Service Insecure Secure Notes Access
POP 110 995 For receiving only e-mail client
SMTP 25 465,587 For sending only e-mail client
IMAP* 143 993 For syncing data across multiple clients e-mail client
HTTP HTTP 80 443 Webmail access (http://webmail.yourdomain)

*IMAP protocol is very sensitive to bandwidth issues, make sure your network or internet bandwidth is of sufficient quality and capacity.

Client-side configuration

  • Authentication: uses both full e-mail address and password e.g. username@yourdomain and password of your email account as default.
  • Incoming Mail Server: mail.domain
  • Outgoing Mail Server mail.domain
  • Supported Incoming Mail Protocols: POP3, POP3S (SSL/TLS), IMAP, IMAPS (SSL/TLS)
  • Supported Outgoing Mail Protocols: SMTP, SMTPS (SSL/TLS)

Internet access

  • webmail: https://yourdomain/webmail

Several ISP’s block port 25 outbound (SMTP) however they normally offer an alternative for relaying/sending mail, if you do not have external mail servers this is an option you can use, otherwise use the secure protocols/ports, if that fails we can give you a custom port to use.

Other Notes

  • Mac Mail IMAP Note: The "IMAP Path Prefix" needs to be set to INBOX otherwise will not be able to store deleted, draft or sent mail on the server
  • Unless you have an SSL certificate needed for extra security (with CFTS this is provided free on most yearly hosting packages)  then you will get SSL Error - Certificate Not Trusted, you can safely ignore this error.
