SMTP Proxy
SMTP is rightfully considered a mail proxy. Although their functionality is limited at this point, they are quite often used for sending mails and protecting your own email box from spam.

- Intermediate SMTP proxies do not store messages.
- They can reject other SMTP connections in real-time (spamming) or analyze the message content with a spam filter or antivirus program, preventing it from reaching the mailbox.
- Advanced SMTP servers can manage the flow, reducing the damage from malicious traffic bursts.
Such servers come in several types:
- Transparent. The client and mail server communicate with each other, unaware of the presence of disguised proxies.
- Synchronous. One client connection equals one connection to the mail server.
- Multiplexing. A connection to the mail server is established only when necessary, and the connection pool is manipulated.
