[solved] Have a list of emails of a specific domain

[joximu]

Hi

well - I think I understood right... but I did not write everything... :-/

One way: in ispcp: as domain user you have the addresses on the page with the mailboxes. - of course the "autoresponder" thing is also there which might be disturbing.
the number of lines you can set as ispcp admin in the settings: "domains per page"...

Or there are the system files: as stated... but you might need to filter them...
grep "@domain.tld" /etc/postfix/ispcp/mailboxes | cut -f 1 | sort
(here you don't have the alias-adresses/forwardings)

if you need another approach you have to write your own solution using the data in the mysql database...
