smtptoxmpp's Introduction

smtptoxmpp

A small XMPP component to relay emails as XMPP messages.

smtptoxmpp runs as a foreground daemon or with systemd socket activation.

Be warned if an email is sent to an address for which there is no XMPP account, it is dropped without error.

Configuration

smtptoxmpp takes the name of a config file as a single argument; an example follows:

[xmpp]
domain = "example.com"
name = "smtp" # the name of the component would then be smtp.example.com
secret = "changeme"
server = "example.com"
port = 5347
# smtpregexp and xmppregexp are optional, in this example emails are addressed
# to the subdomain @xmpp.example.com. The XMPP server only serves @example.com,
# so inregexp extracts what lies before the ampersat and outregexp appends the
# extraction with @locahost. The first pair of () corresponds to $1, the second
# to $2, and so forth.
smtpregexp = "(.*)@xmpp.example.com"
xmppregexp = "[email protected]"

Serving a sub-domain on the same machine as Postfix

Add this to /etc/postfix/main.cf

transport_maps = hash:/etc/postfix/transport Add a line like this to /etc/postfix/transport xmpp.example.com smtp:[localhost]:5225 Then run smtptoxmmp with the -port 5225 option or set systemd to activate smtptoxmpp on port 5225.
