Server settings

The following server settings provide a secure connection by using SSL/TLS encryption:

ProtocolSSL/TLS server nameSSL\TLS port number
POP3 (incoming)mailbox.grindersbox.com995
IMAP (incoming) mailbox.grindersbox.com 993
SMTP (outgoing) mailbox.grindersbox.com 465 or 4650

The following server settings provide a secure connection by using SATRTTLS encryption:

ProtocolSTARTTLS server nameSTARTTLS port number
POP3 (incoming)mailbox.grindersbox.com110
IMAP (incoming) mailbox.grindersbox.com 143
SMTP (outgoing) mailbox.grindersbox.com 25 or 2525

Our email settings are as follows:

  • SMTP server: mailbox.grindersbox.com
    • SMTP server requires authentication
      • Your email address is your user name
      • Same user name & password as POP account
    • SMTP Port can be the default port SSL 465 or 4650 if your having problems sending email
    • SSL
  • POP/Imap server: mailbox.grindersbox.com
    • Your email address is your user name
    • use the default SSL port IMAP 993 or pop 995
    • SSL

Which one should you use? POP or IMAP?

POP3 is an older protocol. It was designed to transfer messages to a client for reading; that client would be some other computer. Once the message was transferred, it would (usually) be deleted on the server, although there is an option to keep a copy on the server at all times.

IMAP is a newer protocol. It was designed to allow one or more clients to connect to a mailbox on a central server. The idea was that the server would continue to store and manage the email at all times, while allowing access from any client that requested it (with the proper credentials).

If you have a choice, generally speaking, IMAP will be superior for the following reasons:

  • you will not have to store nessages to your local machine, which means e-mail lost to a dying hard drive is no longer an issue, nor will it take precious space;
  • downloads are done on-demand, instead of as a batch. Several large emails can take a significant amount of time in POP3, but in IMAP, you will only retrieve what you are attempting to read;
  • once the email is transferred to your client, and unless you specify to leave a copy on the server, that client has the only copy. This means that if the client suffers a storage failure (hard drive crash) your email will be lost;
  • you can organize your email into “folders” as you would on a local client; when you connect with a different client, you retain that structure. This feature is great for Iphone users.

There are however times when POP3 is preferable, such as:

  • The email client you are using doesn’t support IMAP (obviously you need to connect somehow);
  • You fully intend to transfer the message to a different computer and you do not wish to have a copy left on the originating server;
  • POP3 is generally supported more due to its age because there are so many implementations of POP clients out there, although IMAP is fast catching up;
  • your email server may impose quotas that do not make IMAP practical if you have a large amount of email you keep around (Our server has a 20GB limit)
