Subject: [webmin-l] Postfix-Configuration for 'road-warriors'

Hi List!


At the moment I'm in progress to setup a box for ~70 domains with
Webmin/Virtualmin --

can anybody shed some light on me how to configure Postfix to accept
delivery for
'foreign' domains??? (Every help is welcome! Even RTFM --> 1. ...  2.
... 3. ...)


The situation is as follows:

- 1 Server; SuSE9.0; Webmin; Virtualmin; BIND9.x; MySQL; Postfix;
Courier-IMAP; ...
- ~70 domains to setup with about ~300+ users
- Webmin/Virtualmin are working (like always...)
- DNS is working (TNX Jamie!!)
- MySQL (seems to be) working -- I'll have to check it later...
- Postfix/Courier-IMAP is working as it should (for incoming mails...)


Problem is:
- some users are sending their mails _directly_ (*@t-online.de /
*.isp.tld / ...)
- some users (have to / will ?) use *our* server for relaying
- all users are 'dialin'-users (even those with 'non-permanent'
xDSL-accounts)
- POSTFIX isn't an 'OpenRelay' by default/design
- Virtualmin is (only?) creating 'system-accounts', not any sort of *SQL
   (correct if I'm wrong)
- nor is Virtualmin creating additionals 'sender-X-can-relay-to-world'
files or
   databases


Question(s):
- did I overlook some 'basic'-configurations ?
- how can we configure POSTFIX to authenticate allowed senders against
the
   (by Virtualmin) created 'system-accounts' ?
- is anyone using POSTFIX with SMTP-auth against /etc/passwd |
/etc/shadow ?
- is anyone willing to share the secrets with me on how to make it work
?


TNX & have a nice day!!

[Bill James] The first thing that comes to mind is pop-before-smtp (I
use it for a small user base but a lot of road warriors)

See this link for excellent help on setting Postfix for this plus many
other ideas

Check out the Postfix mailing list archives, this has been discussed
there multiple times
