Zimbra standard also includes active sync so your iOS and android device can connect to it like if it was an exchange server. I have dozens of users doing that and the calendars work as intended. I also have a few dozen users connecting to our zimbra server via the Apple calendar program via CALDav protocol and although Apples program is not 100% CALDav compliant it works fine for the things people actually use. They send invites and get reminders for events just fine. For our outlook users there is a connector that allows outlook to connect to our zimbra server as if it were an exchange server. I wasn't aware that thundebird had a calendar component but it works fine for IMAP and POP. I'm not saying it is perfect but if you have a mix of platforms like I do(Windows, Mac, Linux, android, iOS) and have to host the data yourself, I think Zimbra is a decent solution. That being said, I would prefer to use googles offerings. It would make m y job a lot easier. Being an email admin, dealing with spam/phishing/malware, maintaining security patches, OS updates, and hardware sucks. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[...] People want their phone to remind them of their appointments [...] It's a generalization. Not valid for all people. Maybe SOME people want their phone to remind them of their appointsments. My appointments are synchronized from owncloud to Thunderbird and to many (LineageOS-based) smartphones and tablets and >>I<< do NOT want to be reminded on the smartphones and tablets, but ONLY on Thunderbird desktop client.

However, in Thunderbird on Linux and using Mac clients, etc .. and certainly on Windows workstation clients using outlook .. zimbra does not work well. It also does not work well on people's smart phone calendars.

All I did was restart the system. I stopped and restarted postfix, dovecot, mariadb several times over the past couple days. Pretty sure I did a system reboot a time or two. Decided to do one a few minutes ago and now its working. Hate I never found the problem that caused this issue!

Re: [CentOS] Mail has quit working
> > I did find where the mail is going. I found it in /Maildir/new/ Yes, that's how Maildir mail works - delivery to a Maildir folder means that the mail is put in Maildir/new until it is seen, when it is moved to Maildir/cur via Maildir/tmp - it's complicated, but it's necessary in order to maintain appropriate locks on the files when multiple clients are accessing them. > > Still can't login to roundcube. > When you say "can't login" - what is the error? What do the dovecot logs say? You can see where dovecot logs to by looking in /etc/dovecot/conf.d/10-logging.conf - can you see your roundcube install attempting to authenticate?
