Mailman / Postfix Configuration Assistance

I am writing for some help regarding Postfix configuration. I cannot seem to get Postfix configured properly to transfer mail to the mailing list installed on the same server. I followed many steps over the last few days, and the last one I followed is at http://www.postfix.org/VIRTUAL_README.html under the section Mailing Lists. Can someone please look at this and let me know what I am missing? Basically, Postfix has been configured for base email to be sent to xxx@mail-test.company.org and I would like the mail list to use xxx@listtest.company.org. **DYN-DNS** listtest.company.org A 216.111.222.85 listtest.company.org MX 216.111.222.85 listtest.company.org TXT "v=spf1 a ptr mx ip4:216.111.222.85 mx:mail-test.company.org -all" mail-test.company.org A 216.111.222.85 mail-test.company.org MX 216.111.222.85 mail-test.company.org TXT "v=spf1 a ptr mx ip4:216.111.222.85 mx:mail-test.company.org -all" **main.cf** myhostname = mail-test.company.org mydomain = company.org myorigin = $hostname alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases alias_database = hash:/etc/aliases, hash:/etc/mailman/aliases recipient_delimiter = + virtual_alias_maps = hash:/etc/postfix/virtual mydestination = $myhostname, listtest.$mydomain /etc/postfix/virtual: listname-request@listtest.company.org listname-request listname@listtest.company.org listname owner-listname@listtest.company.org owner-listname /etc/aliases: listname: "/usr/lib/mailman/mail/mailman post mailman" owner-listname: ... listname-request: ... **mm_cfg.py** DEFAULT_URL_HOST = 'listtest.company.org' DEFAULT_EMAIL_HOST = 'listtest.company.org' add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST) MTA = 'Postfix' The first part of the log shows the rejection of listtest.company.org -- whereas the second part shows successful transfer to mail-test.company.org **/var/log/maillog** Aug 17 15:46:50 listserv postfix/smtpd: NOQUEUE: reject: RCPT from Mail1.company.org[66.173.196.101]: 554 5.7.1 : Relay access denied; from= to= proto=SMTP helo= Aug 17 15:46:50 listserv postfix/cleanup: D3F93209F1: message- id= Aug 17 15:46:50 listserv postfix/smtpd: disconnect from Mail1.company.org[66.173.196.101] Aug 17 15:46:50 listserv postfix/qmgr: D3F93209F1: from=, size=6670, nrcpt=1 (queue active) Aug 17 15:46:50 listserv postfix/cleanup: F37B120A3B: message- id= Aug 17 15:46:51 listserv postfix/qmgr: F37B120A3B: from=, size=6819, nrcpt=1 (queue active) Aug 17 15:46:51 listserv postfix/local: D3F93209F1: to=, relay=local, delay=0.18, delays=0.17/0.01/0/0, dsn=2.0.0, status=sent (forwarded as F37B120A3B) Aug 17 15:46:51 app02-listserv postfix/qmgr: D3F93209F1: removed Any help would be greatly appreciated.
