That's already happening and it works fine. > - sync their mailstore (by any of several methods - from unseen routers > through GMIRROR, nfs, or shared SAN) Currently the mailstore, with its own MTA, is on a seperate server outside the mx records (it also has imap). I am not convinced about introducing a seperate mailstore on an NFS server or such. And imap wouldn't work very well with it, unless it'd be running locally on the mailstore (I doubt a netapp SAN can do that). NFS for example lacks certain filesystem mechanisms imap needs, so for example opening an imap mailbox shared would break. Anyways, it's that server I am brainstorming about. > - have each box watch the other (checkservice, monit - whatever). > > - IF/AS/WHEN a box sees its twin go offline, it picks up the IP of the > failed box as an alias.
