Hello, I have a system using postfix multi instance feature. The first, main postfix-instance is a nullclient as suggested by http://www.postfix.org/MULTI_INSTANCE_README.html#split
The second instance is for real use. Postfix receive mail and handover them to the dovecot lmtp server. Thats working. The lmtp server supports sieve. One account has activated a vacation rule. So while delivering a mail to this account, dovecot creates a new mail based on the vacation rules. *This one* fail. It is injected in the main postfix instance, which is wrong in this case. I tried to start dovecot with an additional environment MAIL_CONFIG=/etc/postfix-instance2 and enabled alternate_config_directories in main.cf of the first insance. ( http://www.postfix.org/postconf.5.html#alternate_config_directories ) I also configured the userdb to return an extrafield userdb_mail_config=/etc/postfix-instance2. But all produce strance postfix errors I never saw in my last 6 years as postfix-admin. Would it be possible to configure dovecot lmtp server to use an external smtp-server to submit new mails ? Any other Ideas ?
