Hello,
at first: sorry for my bad English, German is my preferred language and I'm not a Linux guru.
I'm not sure about my malman installation. I will show at first some facts:
LAN: our LAN domain is "intern.company.de"
the mail server in the LAN: mail.intern.company.de
on mail.intern.company.de is running open xchange on an UCS (unvention corporate server, a debian)
our external domain is: company.com -> an email address is <name>@company.com and ..@company.de on the same server.
the internal open xchange has so three mail domains : intern.company.de, company.com and company.de
fetchmail is polling the emails from the external mail server
mailman is installed on the open xchange server 'mail.intern.company.de'
My first mailing list is (after mailman) 'about-dummy'. And /etc/postfix/virtual contains: about-dummy@company.com about-dummy about-dummy@company.de about-dummy about-dummy@intern.company.de about-dummy
My first try to receive an email from an external address to this list is failed, because I have to add 'about-dummy@localhost' in virtual. After this entry, the email was received. But why ..@localhost? I saw this in the log file, unknown mailbox about-dummy@localhost.
For mailman I have no Idea about virtual_alias or virtual domains. Only these two lines IMAGE_LOGOS = '/icons/' MTA = 'Postfix' I have added to mm_cfg.py. Is this ok?
And in postfix? Here a short cutout from main.cf: ---snip--- myhostname = mail.intern.company.de mydomain = intern.company.de myorigin = /etc/mailname smtp_helo_name = mail.intern.company.de append_dot_mydomain = no masquerade_domains = $mydomain masquerade_exceptions = root transport_maps = hash:/etc/postfix/transport, ldap:ldaptransport mydestination = $myhostname.$mydomain, localhost.$mydomain, $mydomain, localhost, $transport_maps mynetworks = 127.0.0.0/8 relay_domains = $mydestination relayhost = www.company.de canonical_maps = hash:/etc/postfix/canonical virtual_maps = hash:/etc/postfix/virtual, ldap:ldapgroups, ldap:ldapdistlist, ldap:ldapvirtual, ldap:ldapsharedfolderlocal relocated_maps = hash:/etc/postfix/relocated alias_maps = hash:/etc/aliases,hash:/usr/local/mailman/data/aliases alias_database = hash:/etc/aliases ---snap--- and many LDAP entries from the open xchange installation.
Is main.cf ok? I'm not sure. How looks the right configuration files?
Many thanks and greeting Oliver from Germany
