TCP is
the most commonly used application protocol for HTTP,FTP,SMTP,IMAP,POP3.

TCP ports 143 and 993
, for insecure and secure sessions respectively.
Is mail UDP or TCP?

three use TCP
, and the last two are used for accessing electronic mailboxes. Special records stored in DNS servers play a role as well, using UDP.

What is the IMAP protocol?
Internet Message Access Protocol (IMAP) is
a protocol for accessing email or bulletin board messages from a (possibly shared) mail server or service
. IMAP allows a client e-mail program to access remote message stores as if they were local.
What is POP vs IMAP?
So, what’s the difference between POP and IMAP? POP3 downloads the email from a server to a single computer, then deletes the email from the server. On the other hand,
IMAP stores the message on a server and synchronizes the message across multiple devices
.
Is IMAP safe?
IMAP and POP transmit your username, password, and the contents of all your messages in plain text. This means they can be intercepted relatively easily. However, IMAP and POP can use SSL encryption, which is what is used on encrypted web pages, and
is theoretically quite secure
.
Why IMAP is used?
IMAP allows you to access your email wherever you are, from any device
. When you read an email message using IMAP, you aren’t actually downloading or storing it on your computer; instead, you’re reading it from the email service.
Is port 80 A TCP?

one of the most commonly used port numbers in
the Transmission Control Protocol (TCP) suite. Any Web/HTTP client, such as a Web browser, uses port 80 to send and receive requested Web pages from a HTTP server.
What is the port for webmail?
Modern email servers use
port 587
for the secure submission of email for delivery. For example, if you use an email client software like Outlook or Apple Mail, it most likely is configured to use this port to send your messages.
Is UDP good for email?
This makes
UDP ideal
for things like streaming video where every single packet isn’t as important as keeping a continuous flow of packets from the server to the client. Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important.
Is port 587 TCP or UDP?

Is FTP UDP or TCP?
FTP is
a TCP based service exclusively
. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a ‘data’ port and a ‘command’ port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port.
