I ended up ordering a gen10 plus for $660 off Amazon. The gen10 for $330 seems to have problems actually ordering it. Seller's lose.
I really don't see value in using ClearOS for this application. I don't have a clear information on its email service compared to iRedMail and if it is still CentOS7 based, well I will go with AlmaLinux 9...
Good to see you all again, but my old ClearOS6 server is off, and I will probably wipe the drive then toss it into my spares bin. then hardware is a 10+-yearold Lenovo SFF, heading to recycling.
I have no issue with using hardware which is out of support; been doing it for decades. Afterall, the current hardware will be out of support during the life of the mail server in all likelihood.
For example, CVE-2020-24511 is for an authorized user gaining more privileges. With a mail server, there is only the server userids and admin that could do a lot more stuff.
Security is never ending; it keeps me employed. Keeping the OS current and minimizing exposures there are more the issue and why I may be interested in ClearOS, or go with AlmaLinux.
And if I do this right this time, if needed, I can build a new server with the OS on the OS RAID1 drives and 'just' migrate the data drives.
I was a ClearOS NAS user from ~2013 until 2022 when I finally powered down my last home-build NAS and went with a commercial SOHO product. Not the point here, other than to say I DO have experience with ClearOS and I was a CentOS user from CentOS1 - CentOS7 on both Intel and ARM.
I have been running my own mailserver on an ARM box since 2014 and I am at the age where it is time to stop messing around. I have looked for something off-the-shelf that would meet my multi-domain needs and am kind of focusing on iRedMail, but what RAID1 box and what flavour of CentOS (or turnkey).
So I have pretty much decided that an HP Proliant gen10 Microserver would best fit my hardware needs. SUPPRISE! HPE is ClearOS!
Can I thus not roll and do the OS support myself (e.g. AlmaLinux)?
But I need a solid multi-domain email solution. that is the ONLY use for this box.
can I run iRedMail, or will what is available in the HPE ClearOS provide what I need. For reference, here is what I have done:
I DON'T want to do this anymore. I want to drop in mail and just admin it.
I have Cubieboard2 and Cubietruck that I can easily test on. If you can build on the Centos7 image, and add to it via a specific repo we can easily jumpstart the work. Using the Gnome image would give a nice remote desktop. I have finally figured out vncserver as I explain on my web page.
Cubies are nice because how easy the image install to sata is. I just dd to the sata via usb, then use gparted to adjust partitions as I want.
Noarch rpms are really nice. Unless they have dependencies in EPEL that have compiled. I was burnt with that trying to get Xfce desktop going.
I have some time next week. Then the Jewish Holidays start and I am very stressed until into the 1st week of Oct.
So please keep me in the loop. Meanwhile I have a Zotac Zbox nano...
I tried some searches on "arm", but only found one reference of attempting a port to arm by Sergei Pupykin back in May in the "Clearsync repository missing build tags" thread.
The Centos ARM SIG has made great strides in the ARM images:
https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp (for armv7)
https://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64 (for armv8 64 bit)
I have my own howto at:
and I really need to update:
as it should be easier now than a year ago....
It would be really great to at least have the basic server functions on arm boards for small home office use.
If this has come up elsewhere, please point me to the discussion.
This is a new server with all updates applied.
And the workstation is a recent build and registered with MS. All updates applied.
The server is homebase.home.htt (192.168.192.2)
The client is on the same subnet (192.168.129.77) and can ping homebase.
\\homebase.home.htt on the start programs box opens up explore showing all my shares and I have no trouble opening up public shares.
I have made the registry hack via regedit. I go to Windows Explore> Computer > System Properties > Computer Name, domain, workgroup settings and select Network ID and follow the wizard.
I have tried both HOMEBASE and HOMEBASE.HOME.HTT for the Computer Domain. The error I get is that teh AD DC cannot be contacted.
What do I do to get the computer to join the server?
I have a howto on setting up a Centos7 multidomain mail server at:
This is on a CubieTruck armv7, but it is Centos7 which SHOULD mean that you can install the whole suite on a ClearOS7 box.
This is an improvement on my Redsleave6 mailserver. So I have been using this sort of setup for a lot of years.
Just note that amavis and clamav can eat up 2 cores easily.
Yes, you have the ClearOS CA cert. This shows how to create server certs, using a private CA cert for signing. That is the 'key' part. I have plenty of examples of self-signing certs at:
I need to add running a private CA like the OP is asking.
