Basic settings for use with IMAP and POP email clients and links to detailed instructions for many popular choices.
What you need
- Login information for the email account associated with your client. If you do not yet have an email account set up for your domain, refer to How to create email accounts in SiteWorx.
- The IMAP and POP3 configuration settings and the Nexcess mail server information provided in your Nexcess Welcome Email. If you cannot locate this information, contact the Nexcess support team.
Basic configuration settings for all clients
Username
You must use your full email address for your username, not just the section before the "@." For example, the username for joe@example.net would be joe@example.net.
Incoming and outgoing mail server
If you use a shared or dedicated server, use the server’s hostname; for example, cloudhost-123456789.us-midwest-1.nxcli.net, sip1-123.nexcess.net, or obp1-01.nexcess.net. Do not use any other domain that has a DNS record that points at the mail server or your domain; for example, mail.example.com.
If you use a server cluster, Nexcess recommends using the DNS instead of the server’s hostname for the sake of simplicity. If you prefer to use the server’s hostname, contact the Nexcess Support Team for assistance.
Account type
Nexcess recommends IMAP protocol over POP3 protocol because IMAP generally possesses all the advantages of POP3 and none of its disadvantages. Refer to Email protocols IMAP versus POP3 for more information.
For IMAP, use port 993.
For POP3, use port 995.
SMTP setting
Use port 587 for the SMTP setting on all email clients.
Encryption
Nexcess servers do not support non-encrypted setups. When specifying the settings for the incoming and outgoing server, select SSL/TLS encryption for incoming and STARTTLS for outgoing.
Client-specific information
For specific installation instructions regarding your particular client, select the corresponding link.
