Yes, this is not a Postfix issue but a mail store issue. Nikolaos, what mail server are you using? Cyrus, Dovecot, other? As Viktor points out, building an HA mail server is not trivial. But we can probably point you to HA docs, and mailing lists, relevant to your mail server if we know what it is. -- Stan
