Perdition use cases

Perdition is a proxy for the POP and IMAP protocols that allows a user to connect to any Perdition server, regardless of their account's zimbraMailHost, and use a POP or IMAP client to access their mail.

Perdition is useful in multi-node installations, where several mailstore servers may be accessed through the same hostname (either via round-robin DNS or a load balancer).

Perdition is also useful for offloading the SSL connection from the tomcat server, and handling it in the proxy. This can reduce the load on the mailstore server, as well as work around some IMAP SSL bugs.

Note: Perdition only proxies IMAP and POP - it is not an HTTP/S proxy.

Perdition can proxy these services:

  • IMAP (default port 143)
  • IMAPS (default port 993)
  • POP3 (default port 110)
  • POP3S (default port 995)

Setting the ports

"Real" and proxied ports

In any perdition setup, there are 2 ports defined for every service.
