Split_Domain split-domain-os-x-postfix Migration issue with split domain & multi-servers
all users only know mail.example.com but want to get mobile service and webmail from zimbra,
my issue is
how to make the user
foo@example.com can open his old mail box with ton of mail and spam at both mail server (in this scenario webmail.example.com and mail.example.com) (*** i don't like migrate his mail to new mail server because his 3 gig mailbox with rule of folder filter and spam is to big effort for the looser guy like him (4year archive***)
ext;
like forward mail for "some users" @example.com in host
mail.example.com to "existing users" @example.com in host
webmail.example.com but keep the mail copy so the users can have identical mailbox in mail.(ME) and webmail.(Zimbra)
in the external link,
user
foo@example.com at
mail.example.com didn't got any mail because all mail being re-route to
foo@example.com at
webmail.example.com
previously i used imapsync to mirroring, but this make un-sync because not real time sync
