[Mailman-Users] Bounce Message, ReturnPath/ErrorsTo issue

[Michael Kabot]

(To the list this time !)

Mark,

Thanks for the quick response and pointers to the right place in the code.

I have left Plesk managing the Mailman lists to try to keep continuity on my
server.  It looks like Plesk is not doing a good job of properly configuring
Mailman or the lists.

The following is an excerpt from my mm_cfg.py

	from socket import *
	try:
 	   fqdn = getfqdn()
	except:
 	   fqdn = 'mm_cfg_has_unknown_host_domains'

	DEFAULT_URL_HOST   = fqdn
	DEFAULT_EMAIL_HOST = fqdn

	add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

	add_virtualhost('lists.[DOMAIN1.COM]')
	add_virtualhost('lists.[DOMAIN2.COM]')
      [ADDITIONAL LINES FOR EACH OF THE HUNDREDS OF DOMAINS I HOST]

If there is no 2nd parameter to add_virtualhost, will it create one from the
1st parameter?  I checked, there are no duplicate add_virtualhost lines.

It looks like getfqdn() is where the WRONGDOMAIN.COM is coming from.

Either way, I would rather have a bounced bounce message go
postmaster@[SERVER.COM] than a domain specific email address or the
mailman-bounces address.  Looks like I can "affect" that in the owner code
given my Mailman configuration.

Thank you for your assistance !

Mike

| 
| 
| The scripts/owner script which receives mail addressed to -owner sets
| 
|    envsender=Utils.get_site_email(extra='bounces')
| 
| (this is in Mailman/Utils.py). This in turn gets the domain part of the
| address in a complex way (see Utils.get_domain()), but in this case,
| it boils down to
| 
|   - get DEFAULT_URL_HOST
|   - look up the corresponding email host in mm_cfg.VIRTUAL_HOSTS
|     (the dictionary built by add_virtualhost())
| 
| So it looks like you probably have more that one add_virtualhost()
| entry with the same url_host argument (either DEFAULT_URL_HOST or its
| literal value.
| 
| This doesn't work. VIRTUAL_HOSTS is a Python dictionary (hash table)
| with key = the first add_virtualhost() argument and value = the second.
| 
| So, if you have something equivalent to
| 
| add_virtualhost('www.example.com', 'example.com')
| add_virtualhost('www.example.com', 'example.net')
| 
| the second entry replaces the first.
| 
| All url_hosts and all email hosts in
| 
| add_virtualhost(url_host, email_host)
| 
| lines need to be unique for it to work as intended.
