POP3, IMAP4 and SMTP

PentaMails supports all standard email protocols. This means you get to keep using your favorite email apps while using our service. POP3, IMAP, & SMTP are the most popular, and they allow users to check and send email via desktop email clients like Outlook and Mozilla Thunderbird, as well as wireless devices like BlackBerry, Treo, and the iPhone.

POP3

Post Office Protocol (Version 3) is what most users need and use today. POP3 is a client/server protocol in which email is received and held on a mail server. Periodically, you check for mail on that server and then download it to your email client. POP3 is the standard protocol built into practically every email client. This method is well-suited for users that don’t want to store email messages online.

IMAP4

Internet Message Access Protocol (Version 4) is another popular way to access email messages. With IMAP, messages and folders are always stored on the mail server. When users access their email, they are working directly with these messages. This means that any updates made to the email, such as moving, flagging, or marking a message as unread, is stored on the server.

IMAP is a convenient option for users who need to access their email online from multiple clients at multiple computers or locations.

Our IMAP server supports IMAP IDLE, which provides real-time push support for IMAP applications, alerting you the second you have new mail... which makes it very powerful for users on the go.

SMTP

Simple Mail Transfer Protocol is the standard protocol for sending email messages across the Internet. It is also commonly referred to as the outgoing mail server. Our SMTP servers are configured to require SMTP Authentication. The servers themselves perform two important functions. They verify that anyone attempting to send outgoing email through the SMTP server has the right to do so. Then, they send the outgoing email. If undeliverable, the mail gets sent message back to the sender.

SSL and TLS Encryption

We provide SSL and TLS encryption for POP3, IMAP, SMTP, and the PentaMails webmail client. Basically, this encrypts your data so that others cannot view it. Our servers also support opportunistic TLS, which allows your incoming and outgoing email data to be encrypted as it travels through the internet. This is very important for passwords and confidential emails.

Supported RFCs

RFCs are standards for email communication between servers and email clients. These standards are approved by the Internet Engineering Task Force (IETF) and are known as RFCs. These standards cover SMTP, POP, and IMAP, among other Internet technologies.
