Hi, For some years I run my own mailserver. I just added a mailing-list service. I'm testing it and it seems to run fine, except I can't send anything to external users. External means email-addresses not on my mail-server. The postfix log shows this : Aug 20 13:37:36 neptunus postfix/qmgr[4431]: E6987101699: from=<someone@somewhere.com>, size=1686, nrcpt=1 (queue active) Aug 20 13:37:36 neptunus postfix/pipe[4571]: E6987101699: to=<testlist-request@lists.example.com>, relay=mailman, delay=0.78, delays=0.21/0.02/0/0.55, dsn=2.0.0, status=sent (delivered via mailman service) Aug 20 13:37:36 neptunus postfix/qmgr[4431]: E6987101699: removed Aug 20 13:37:38 neptunus postfix/smtpd[4574]: connect from localhost[::1] Aug 20 13:37:38 neptunus postfix/smtpd[4574]: NOQUEUE: reject: RCPT from localhost[::1]: 554 5.7.1 <someone@somewhere.com>: Relay access denied; from=<testlist-bounces@lists.example.com> to=<someone@somewhere.com> proto=ESMTP helo=<[127.0.1.1]> Aug 20 13:37:38 neptunus postfix/smtpd[4574]: disconnect from localhost[::1] Postfix gets it's domains and users from a MySQL database (postfixadmin). In the postfix config I have : myhostname = mailbox.example.com mydestination = $myhostname, localhost.$mydomain relay_domains = $mydestination, lists.$mydomain I hope my name-mangling has not destroyed "evidence". Can anyone point me to the parameters I should look at ? I seem unable to find what relay-option I have to set/modify. I tried modifying mydestination by adding lists.$mydomain after $myhostname but that does not work. I also added an alias-domain in postfixadmin. Both did not work : the addresses in lists.example.com became unknown. Thanks for any help.
