Hello all. I am attempting to use Mailman-2.1.5 with Courier-0.46 and I 
haven't had much luck as of yet in terms of getting it going. Right now 
I have the mailman (site list), and a list called Igors_list which I am 
currently working with. The aliases I currently have defined are as 
follows: igors_list:             |/usr/local/mailman/mail/mailman post 
igors_list
igors_list-admin:       |/usr/local/mailman/mail/mailman admin 
igors_list
igors_list-bounces:     |/usr/local/mailman/mail/mailman bounces 
igors_list
igors_list-confirm:     |/usr/local/mailman/mail/mailman confirm 
igors_list
igors_list-join:        |/usr/local/mailman/mail/mailman join igors_list
igors_list-leave:       |/usr/local/mailman/mail/mailman leave 
igors_list
igors_list-owner:       |/usr/local/mailman/mail/mailman owner 
igors_list
igors_list-request:     |/usr/local/mailman/mail/mailman request 
igors_list
igors_list-subscribe:    |/usr/local/mailman/mail/mailman subscribe 
igors_list
igors_list-unsubscribe: |/usr/local/mailman/mail/mailman unsubscribe 
igors_list

Note that in the aliases file everyone is on its individual line,, it 
just got wrapped because of the text editor I'm using for this message. 
I tried sending a test message to igors_list at lava-net.com (after 
subscribing myself through the admin interface). In my maillog file, I 
got the following: Dec 19 10:42:09 shadwiga courierd: 
newmsg,id=001A8123.41C5A151.000072AE: dns; localhost (localhost 
[127.0.0.1])

Message delivered.
Dec 19 10:42:09 shadwiga courierd: 
completed,id=001A8123.41C5A151.000072AE

However, in /usr/local/mailman/logs/smtp-failure I get this: Dec 19 
10:42:11 2004 (29012) Low level smtp error: (-2, 'Name or service not 
known'), msgid: <mailman.7.1103470930.29014.igors_list at lava-net.com>
Dec 19 10:42:11 2004 (29012) delivery to igueths at lava-net.com failed 
with code -1: (-2, 'Name or service not known')
Dec 19 10:42:11 2004 (29012) Low level smtp error: (-2, 'Name or service 
not known'), msgid: <mailman.8.1103470930.29014.igors_list at lava-net.com>
Dec 19 10:42:11 2004 (29012) delivery to igors_list-owner at lava-net.com 
failed with code -1: (-2, 'Name or service not known')

I've been googling variants of this error message. One sollution I found 
was to make sure there was an entry for localhost in /etc/hosts, and I 
already have that. Another one was to set 
SMTP_MAX_SESSIONS_PER_CONNECTION to a value greater than 0. I tried that 
and I still got the same message in the smtp-failure log. Should I 
perhaps try setting MTA to something like Sendmail, since Courier is 
able to somewhat emulate it? Currently I have it set to Manual. I also 
have DELIVERY_MODULE set to SMTPDirect. Is there any way I can turn up 
Mailman's logging so that I might be able to figure out what it doesn't 
like? Thanks!
