I have a following situation:
1.My ISP hold for me a virtual domain(all mail for *@mydomain.ru falls in one
mailbox on ISP mailserver)
2.I have three networks with non-internet domains: company ; filial1.company ;
filial2.company, where mail.company is gate for mail from/to inet & from/to
filial*.company. The hosts mail.filial*.company are intermittently connected
to mail.company and are mailservers for their domains.
The problem is: how can I hold messages for filials on main server not in same
queues, so when filial connects to main server, only mail for this network
is going to delivery?
