IMAP and POP3 - definitions

What Is the Difference Between Imap and Pop in My Email Client?

IMAP (Internet Message Access Protocol): 

  • Stores email on a mail server and retrieves it to your client.
  • Allows management of email on server from various email clients and webmail.
  • Limited to email quota (Hostica's email quota can be changed up to your total free space on your account. Simple and Simple Plus have 30GB allotted to the plan.)

POP3 (Post Office Protocol Version 3): 

  • Downloads local copies of your emails and deletes the originals from the email server. 
  • Can only be attached to one computer, it cannot be accessed from multiple clients or webmail.
  • Unlimited space, only limited by the size of your computer's hard drive.

Hostica Recommendation:

Unless you are going to be using a massive amount of data (I.E. Over 2-5GB in New Plans) you will want to use IMAP as it allows you to access your email from the cloud. POP3 is good if you have a lot of emails constantly coming in and you have gone over your quota.
