Hi there, We're using Postfix for quite a while now as our default mailsystem for our world-wide organisation. We are very happy with the setup and working without any problem.
Recently we purchased a Mailarchive systen (mailarchiva) to create an archive of our mails. We installed two of them; one on location A and one on location B. In Postfix, on our main mailserver, i added the following parameters to send the emails to our two mailarchive servers on location A and location B: smtpd_milters = inet:81.x.x.x:8092 inet:217.x.x.x:8092 milter_default_action = tempfail milter_connect_timeout = 10s This works perfectly without any problems. the question raised, what if the connection between the mailserver and location B is down. Is the email delivered to the mailarchive system on location A, but not location B? Will the emails not be delivered to location A and location B? etc etc. So lot of questions. Our goal is to move the emails to the hold queue if one of the mailarchive servers (location A or location B) isn't reachable by the postfix system. Then, if the connection is restored between Postfix and the mailarchive server(s), release the mails from the postfix hold queue and deliver the emails as normal to the two mailarchive servers on both locations. This way we can keep both mailarchive servers in sync. Can this be done with the 'smtp_default_action = quarantine' parameter? Thanks in advanced. Regards, Roland de Lepper
