This is a collection of information to help you use and manage your email accounts provided with your CommerceV3-hosted website.

Server settings

These settings will need to be added to whatever program you use to access email (Outlook, Outlook Express, Thunderbird, Mail, etc.)

  • Incoming mail server (POP): (port 995, SSL-enabled)
  • Incoming mail server (IMAP): (port 993, SSL-enabled)
  • Outgoing mail server (SMTP): (port 465, SSL-enabled)
    • Some service providers may block port 465 from working on your network. If this is the case, alternate ports are 587 and 8025.

DNS configuration changes

These changes will need to be added to your domain's DNS server(s), often hosted at your domain registrar or at CommerceV3. If you don't know where your DNS servers are located, please contact us or have your technical representative do so, and we can assist.

Sending Mass Emails

Any email sent from your domain's personal mailboxes (whether your own account or a general one such as can go to a maximum of 249 recipients at once. This restriction is imposed by Rackspace as their terms of service specifically prohibit the sending of bulk mail from the standard mail servers. Identical or extremely similar emails sent to 250 or more addresses are considered bulk email, and not allowed as it could cause the mail servers themselves to be throttled or blacklisted by external providers (Gmail, Yahoo, Hotmail, AOL, etc.). If you need to send out newsletters or other emails to large groups, you will need to either send them as an email blast, or use a different service provider altogether.
