I try to inject some mails from a /var/spool/imap/ - dir to a zimbra-account as it is described in some threads in this forum.
Basically this is working perfecty, but only for some mails and never for all. The following errors do occur:
I tried to "try again" several times as the errormessage requested, but the result was similar - some more or less mails were injected - but not all.[error] Delivery failed msg=5216. email@example.com response=451 4.0.0 Temporary message delivery failure try again
any ideas out there?
thanks in advance
p.s.: unfortunally the original imap-server is'nt availabe - just the directory with the mails - so i can't use a imap-sync tool :-(
