    I don't see a problem with this, Matt. The only way you could be more secure would be if you had a separate server for your mailstore from the one that handled your webmail, and that's normally only...

    No, I'm afraid that can only be done on the device that is doing the NAT service. If your router doesn't support SNAT (and many don't), you are left with only four choices:

    This is a pretty old security issue, back in the 4.x series. The user's profile says he's using 5.0.9, which is WAY beyond when this was patched, so it should not be an issue.

    I may be guessing too much, but in similar settings where I've set these things up, the problem has been that although you're port-forwarding INCOMING traffic, your OUTGOING traffic is going from a...

    Actually there's something else you ought to look at. Notice this part of your SA headers:

    Two realtime blacklists list your IP. Though you've whitelisted yourself, others who use those...

    Well, sure, this at least means that my worries about you getting lumped with the spammers for a shifting IP should not be a problem. But again, you'll have to set up the MX records on DynDNS; those...

    Hey ejecthunter,

    I'm afraid I won't be much use to you; as I said to the other poster, I haven't actually set up a DynDNS -based Zimbra myself, I merely pointed out those wikis. All my own Zimbra...

    Mike, as to syncing your mobile, that's not entirely true. I have FOSS and two different kinds of users sync to it. One, Blackberry users with BIS sync using BIS-thru-webmail, and two, Windows...

    You are quite right, Mark, that DR is the weak link in local hosting. My two clients have responded differently to the same instructions from me. One of the two has a backup box in a separate...

    That's not the file where they are. local.cf is the last file parsed, so any tweaks you put in there (your own custom stuff) overrides the settings in any of the other SA files, but you won't find...

    Hey Kazoo,

    As I'm sure you know, the spam engine scores mail on the basis of various header and/or content. I'm not at a Zimbra machine at the moment to check, but I would have thought there's a...

    A quick google suggests that IMAP4 is backwards compatible with IMAP2, so 4 would be my first choice based on that. For the actual guts of Zimbra I'll defer to the people who understand...
