Owncloud and nextcloud support federation.

complete ownership of their calendar data.

I'm running a few bone-headed mail servers for schools and small
companies. They're all bone-headed setups on CentOS. I'd say mail
servers are not the easiest thing to configure under Linux. Anyway,
here's all the ingredients I'm using.

Zimbra's calendaring component is also a CALDav compliant server. Users can 
also share their calendars either via the zimbra web client(public, or 
restricted to an email address with a password), or exporting the calendar to 
an ICS file. CALDav compliant calendar clients like Apples calendar app on Mac 
and iOS can subscribe or connect to the zimbra server using its 
https://zimbra.example.com address. The Zimbra web client interface for using 
and managing calendars is just as easy to use as googles calendars.

Just to chime in, I'm using Fruux.com for a client, and while it's not per se 
an open source service, it works really really well and uses open source 
protocols for its operation (CalDAV and CardDAV). They also have great central 
administration, even if it's all local accounts. They use SabreDAV as the 
foundation for the service, hence I think it's worth mentioning.

While I agree with the above, it doesn't really address Johnny's
question, which is which open source calendaring projects can compete
with Google calendar for users' ease of use?  If I give my users Zimbra,
and they hate it, then what?  For simple email use, there are plenty of
clients which can talk IMAP/SMTP to a linux server, but the options for
calendaring (and ''groupware'' in general) are much sparser.

It's a hard question, and each organization needs to weigh their privacy
concerns against their users' requirements.

Your points are valid for sure .. but if you are not encrypting your
email, then all of it is likely being scanned and saved anyway.  Any
router along the way can log packets and see whatever is transmitted
that is not encrypted.

Most of the world uses android phones (I think it is like 75% now) and
all the mail that goes there is available to google as well, right?

Not to say I like it .. I don't.  But people want it to work, work in a
user friendly way and convenient access from everywhere .. and from
their phone, their home pc, while traveling, etc.

[CentOS] Is there any way I can deploy cPanel web hosting control panel with Microsoft Exchange 2016 groupware behind one static public IP?

[Turritopsis Dohrnii Teo En Ming]

Good evening from Singapore,


Is there any way I can deploy cPanel web hosting control panel with Microsoft 
Exchange 2016 groupware behind one static public IP? Or do I need 2 static 
public IP addresses at the minimum? With Exchange 2016 groupware taking up 
HTTP, HTTPS, IMAP, IMAPS, POP3, POP3S, SMTP, and SMTP/S ports, I personally 
don't think I can deploy cPanel behind the same public IP as Exchange.


Please advise. Perhaps you have a brilliant idea. This is for experimental, 
testing and laboratory purposes.


Thank you very much.

Yep. That's why I refuse to have a google account, and why I recommended
against it for business use. I have no knowledge, but even if you pay
google for a "private" business account, I have next to no trust that they
do not have something scanning for info to sell, or market to - we all
*know* they do that to all free email accounts.

"First, do no harm"? Long gone, eaten by their marketing dept, which is
why the signal-to-noise ratio has gone *way* down in the laft five years.

I'll stop the rant now, too, it's OT for the list.

Well said. I feel that too many people today have forgotten (or, more
likely, never learned) these lessons from history. People give away
their personal and supposedly private information too easily and, I feel
certain, will come to regret it (some already have come to regret it).

Don't get me wrong.  I've run qmail, postfix, and zimbra mail servers
with IMAP, along with webmail front ends (roundcude, squirrel mail,
etc), for windows, mac and linux clients for several companies (all on
CentOS of course :D) .. I just don't think that calendaring that I have
seen is as user friendly as google calendar (for example).  But I'm all
for people running mail servers on CentOS (or any other Linux) if they
want !

[CentOS] Logwatch inconsistency

[Adrian van Bloois]

Hi all,
In my logwatch config I clearly state only too report on Yesterday.
The funny thing is that in the MailScanner section the number of mails
scanned is different thant th number reported in the postfix section to
be put on hold.
Ik I grep the Requeue statements in the MailScanner logfile this is
exactly the same number as the scan result of Hold in the postfix
logfile and is equal to the number reported by logwatch in the
MailScanner section.
How come postfix reports a lot more being put on hold than the real
number?
There is at least some inconsistency in there.

Adrian
