Develop SMTP, IMAP, POP3 services with Java

I need Java services with spring boot to talk to SMTP, IMAP, POP3 servers to get inbox email list, gen an email, send email, delete email, reply(All) email, forward email, tag email. Just backend service development needed. Our UI will invoke these services to manage the emails. For email server we are using Zimbra. So services will talk to Zimbra.
