SYNOPSIS

koushin [options...] <upstream servers...>

DESCRIPTION

koushin is a simple and extensible webmail. It offers a web interface for IMAP, SMTP and other upstream servers.

At least one upstream IMAP server needs to be specified. The easiest way to do so is to just specify a domain name:

koushin example.org

This assumes SRV DNS records are properly set up (see RFC 6186).

Alternatively, one or more upstream server URLs can be specified:

koushin imaps://mail.example.org:993 smtps://mail.example.org:465

The following URL schemes are supported:

imaps (IMAP with TLS), imap+insecure (plain IMAP)
smtps (SMTP with TLS), smtp+insecure (plain SMTP)
https (CardDAV and CalDAV over HTTPS), http+insecure (CardDAV and CalDAV over plain HTTP)
carddavs (CardDAV over HTTPS), carddav+insecure (CardDAV over plain HTTP)
caldavs (CalDAV over HTTPS), caldav+insecure (CalDAV over plain HTTP)

-theme: default theme (default: no theme)

-addr: listening address (default: ":1323")

-debug: enable debug logs and print IMAP network activity

-h, --help: show help message and exit
