Description
Ubuntu's mail stack provides fully operational delivery with
safe defaults and additional options. Out of the box it supports IMAP,
POP3 and SMTP services with SASL authentication and Maildir as default
storage engine.
Info
This is a rudimentary start at a workable postfix charm. It
doesn't support scaling yet.
Charm accepts number of options, including MTA type, FQDN,
mynetworks, root, relayhost and destinations.
Options
mtatype:
1 - Internet site; fully functional SMTP that delivers
e-mail directly to destination servers
2 - Internet with smarthost; fully functional SMTP
that delivers all e-mail to a relayhost
3 - Satellite system; SMTP that delivers all e-mail
to a relayhost and doesn't accept incoming e-mail
4 - Local only; local SMTP that delivers e-mail only
on local server and doesn't accept any incoming
e-mail
fqdn: FQDN of the host
IMPORTANT: whenever the config is changed, one
needs to specify this option, otherwise
default (localhost) will be used
relayhost: relayhost/smarthost for delivering email
destinations: domains for which MTA will consider itself
as a final destination
root: account to which all root and postmaster e-mail
will be delivered
IMPORTANT: whenever the config is changed, one
needs to specify this option, otherwise
default (nobody) will be used
mynetworks: IPs or IP ranges from which SMTP will accept
e-mail without the need for authentication
