Would any of you know if the following scenario is "doable"?
We run an old Exchange 2010 infrastructure at my work, and there is no way
they are going to spring for newer: getting them to go from 2003 to 2010
was an ordeal...
Could I set up an Ubuntu Postfix "relay" server between Exchange and the
Internet, that also permits one particular mailbox to be accessible from a
Dovecot install on the same server (as well as relaying the mail for that
mailbox to Exchange)?
Yes/no and pointers most welcomed.
I'm thinking about running a small web & email server at home. We have a fixed IP address (only IPv4, we don't have an IPv6 address).
I'm wondering if anyone knows of any issues we might come across. For instance, will people like spamhaus recognise it as a residential IP and blacklist it because of that?
My own stupid fault for blindly following tutorials in the dim and distant
past (2019) I guess and not then "backing that up" with learning exactly
what it was you just did...
I had a very small "ZFS infrastructure" set up. Small VM on a XenServer
install; worked beautifully.
USB disk that housed the XenServer install died, no more metadata/config,
but all the VHDs were safely stored on external NFS disks. "Burned" a new
USB on newer XCP-ng, started building new VMs. Nothing lost but time...
When it comes to the ZFS volumes I find myself with 6 VHDs for one
"mirrored pair", and I don't entirely know how to "attach" them to see the
content/figure out which two are the current pair.
I have the VM these ZFS VHDs belong to reinstated (bless Linux and
/etc/hostname), but my novice ZFS skills ran out long ago. Is there a
"simple" way to RO mount an individual zpool member (from a pair) and see
what's on it? I'm happy enough going one VHD at a time if it's possible...
This is directly a "work query", but I'm hoping there are some folk out
there with way more Exchange knowledge than me.
When we set up Exchange 2010 for work, we somewhat followed MS "best
practice guidance" and made a DAG between the two VMs, and it's been way
more trouble than it's worth on more than one occasion.
Since we really do need to be upgrading to a newer Exchange now, is it
possible to go from a DAG setup back to a single server on a newer Exchange?
