i apologise in advance for my bad English, i hope you can understand me, but above i hope you can help me
I'm not an ufficial mta and the mail send to my domain are deliver in my isp server first, and every 15 min i fetch the mail from this server to my local zimbra server.
I have defined a sender_bcc rule, in postfix that when someone from my domain send a mail, a bcc are sended to anothe user called _user. For example
the _user is like a backup user, however the _users are not defined in my isp server, in this server is only defined user1, user2, user3, but not _user1, _user2, _user3.
When i normally send an e-mail to another user in my doman there are no problem, but the e-mail are deliver locally, and everithing works so fine.
i'd like to find a method for deliver the email from local user to the isp server, and i think that the high priority is the best method.
For implement this i do a header_check in postfix conf directory like this:
/^X-Priority: (1|2)/ FILTER smtp:myispserver.mydomani.com
but my isp server respond that the _user not exist, and that is right, because this user not exist.
Id like to create something like this:
me -> email@example.com ---> zimbra
me -> firstname.lastname@example.org -> zimbra
email@example.com -> myispsmtp
Help me please.
Thanks in advance
