To connect to a mail server using the command line, you can use a variety of commands depending on the type of mail server and the protocol you want to use. Here are a few examples:

POP3 (Post Office Protocol version 3)

• telnet mailserver.com 110 (replace mailserver.com with the name of your mail server)
• openssl s_client -crlf -connect mailserver.com:110 (use SSL/TLS encryption)

IMAP (Internet Message Access Protocol)

• telnet mailserver.com 143 (replace mailserver.com with the name of your mail server)
• openssl s_client -crlf -connect mailserver.com:143 (use SSL/TLS encryption)

• telnet mailserver.com 25 (replace mailserver.com with the name of your mail server)
• openssl s_client -crlf -connect mailserver.com:25 (use SSL/TLS encryption)

Microsoft Exchange

• mstsc /v:mailserver.com (connect to the Exchange server using Remote Desktop)
• powershell -Command "Get-Mailbox -Server mailserver.com" (use PowerShell to connect to the Exchange server)

Other options

• mutt -F imap://user:[email protected] (use the Mutt email client to connect to the mail server)
• msmtp -a user -p password -F imap://mailserver.com (use the MSMTP email client to connect to the mail server)

Note: Replace mailserver.com with the actual name of your mail server, and user and password with your actual email account credentials.

Also, be aware that some mail servers may require authentication or other settings to connect. You may need to consult your mail server's documentation or contact your system administrator for more information.
