| Simplicato supports POP3, IMAP4, and SMTP/ESMTP Protocols with or without SSL and TLS. Simplicato’s support of SMTP with TLS provides an extra layer of protection for companies that send or receive sensitive information over email.

| POP3 is the original and oldest form of message retrieval. It was created when internet connections were unreliable and uncommon. POP3 client software connects to the server and downloads all messages and attachments which has been received since the last connection. Once all messages are downloaded, they can be read at the users discretion.
Since all messages are downloaded to a single system, messages are not available any longer on the server. In which case, POP3 clients are encouraged to switch to IMAP for better service, reliability, as well as the ability to back up their email boxes.

| Internet Message Access Protocol (IMAP), is an email protocol where the messages are kept on the mail server, including the sent messages, when the client is appropriately configured. IMAP is used by businesses and email users that need to access their mail from multiple locations and/or by multiple users of the same mailbox. Most email clients that support POP3 also support IMAP. Simplicato’s Webmail Application is based on IMAP. The biggest advantage of using IMAP for wireless devices is that it does not require that all messages be downloaded in order to view specific messages. The email user can select the specific message he wants to read and then it will be downloaded. In this way, IMAP provides fast access to the desired email.

|
| Simple Mail Transfer Protocol (SMTP) is the standard for email transmissions across the Internet. The transmission can be between two SMTP servers or between a mail client and an SMTP server. SMTP uses port 25 as a standard. Simplicato’s outgoing SMTP servers are additionally configured to send mail using port 2525 or port 587 to overcome the blocking of port 25 by most of the large ISPs. Simplicato’s outgoing SMTP servers require SMTP Authentication, a username and password, to prevent unauthorized use (commonly referred to as "Open Relay") of our servers.
