Difference between POP and IMAP settings
POP - an internet standard for retrieving email. POP stands for "Post Office Protocol." May also be referred to as "incoming mail."
POP is a one-way communication path. This means that when you access your email from your computer or other local device, your email client (such as Outlook or Thunderbird) will save a local copy of the email to your computer, then delete the original from the mail server. Email accessed using POP ties it to a specific computer or device, thus you will be unable to view your webmail from multiple sources. However, POP is useful for storing local copies of email to be read offline or when not connected to the internet, as well as for ensuring that your webmail mailbox in MailCentral will retain plenty of storage room for accepting more email in the future.
IMAP - an internet standard for retrieving email. IMAP stands for "Internet Message Access Protocol." May also be referred to as "incoming mail."
IMAP is a two-way communication path. This means that when you access your email from your computer or other local device, any changes that are made will be synchronized with your webmail on the mail server. For example, if you log in to MailCentral, create a new folder in your webmail, then put a message into that folder, this change will instantly and automatically appear in your email client (such as Outlook or Thunderbird), and on your mobile device. Also, if you are at work and you begin a message then save it, it will still be there in your mailbox when you log in from a different email client, such as one on your home computer.
IMAP provides a better method to access your mail from multiple devices, say from work, home, and your mobile, through two-way syncing capabilities between your mail clients and the FatCow mailbox. However, because IMAP saves all your messages on the server, be sure frequently clean up your mailbox, deleting old messages and saving the ones you want to keep to a local computer.
Email server names and ports
The Email Server Names settings are:
- Incoming Mail Server - pop.example.com OR imap.example.com
-
Outgoing Mail Server - smtp.example.com
where "example.com" is your hosting account's PrimaryDomain, which is set in DomainCentral
NOTE: Please refer to the Difference Between POP and IMAP settings article to determine which incoming mail retrieval standard is a best fit for your current needs.
The email server ports are:
- POP: 110
-
IMAP: 143
- SMTP: 587
For assistance regarding configuring POP/IMAP email for an iPhone/iPad or Android device, please refer to the appropriate article:
Configure email server names and ports for SSL
SSL (Secure Socket Layer) is a protocol that transmits information over the Internet in an encrypted form for security purposes. POP/IMAP/SMTP over SSL encrypts all data exchanged between your mail client and the FatCow mail server with a digital security certificate to protect your password and messages.
To send and receive email securely using SSL, follow these general steps. Refer to the online help within your mail client for specific instructions on where to set SSL options.
- Use a mail client that supports SSL. Most recent versions of mail clients support SSL. Some older versions do not. The following clients support SSL:
- Eudora version 6.1.x and up
- Outlook Express version 5 and up
- Outlook 2000 and up
- Netscape Messenger versions 4.5 and up
- Entourage 2001 for OS 9 and V.X for OS X
- Mac OS X Mail version 1.2x and up
- Apple Mail
If the mail client that you are using is not listed, please refer to that email client's online help for further assistance with SSL support. - In your mail client, select the incoming/receiving mail option for using SSL (such as "Use SSL" or "Use secure connection (SSL)"). Most clients will set the port automatically when you select the SSL option.
NOTE: This is not the same as "Secure authentication."
- Make sure that the port is set to the correct value:
-
POP: 995
OR
-
IMAP: 993
NOTE: Please refer to the Difference Between POP and IMAP settings article to determine which incoming mail retrieval standard is a best fit for your current needs.
-
POP: 995
- Select the outgoing/sending mail option for using SSL (such as "Use SSL" or "Use secure connection (SSL)").
- Verify that the SMTP server port is set to 465
- Verify that your Email server names are:
- Incoming: pop.fatcow.com OR imap.fatcow.com
-
Outgoing: smtp.fatcow.com
