My mailboxes are on a Dovecot (IMAP) server.On DNS there is an MX record pointing to the server.To read the mail I use Roundcube.If the server is down, I lose the new mail. I would like to do two things, alternatively. First option.1) I keeep the mail on the provider's server, restoring the original MX record.2) Dovecot does not receive the mail, but should go to download it.3) I can access the server with Roundcube to read the downloaded mail, but if the server is down I can always go to read the mail on the provider's server with its webmail Second optionI install a second mail server and the two have to replicate the mail.But I don't know how to do it, so I need a guide with instructions.Furthermore Roundcube would always access only one server and if this is down, how can I connect to the second one?This is a typical situation for webmail like Yahoo, Outlook or GMail, but I'm not Yahoo, Microsoft and Google ;)
Thanks in advance for any advice.
