Topic: Sudden Loss of Connectivity and Responsiveness

======== Required information ====
- iRedMail version: 0.9.2
- Linux/BSD distribution name and version: CentOS release 6.7 (Final)
- Store mail accounts in which backend: MySQL
- Web server: Nginx
- Manage mail accounts with iRedAdmin-Pro? No
- Related log if you're reporting an issue: Currently Unknown Issue
====

Hello,

I have been making my transition from Outlook365 to Mozilla's Thunderbird. I created a temporary account through iRedAmin's web-based admin panel, and began to add the account's settings - no luck. The account was not connecting and Thunderbird was reporting "Thunderbird failed to find settings for your email." so I thought maybe it was something with Thunderbird.

It turns out now that none of my and my team's Email accounts are connecting and that my iRedMail's admin panel is no longer live and accessible. I've restarted my VPS without any luck.

This is what I'm starting with:

[root@mail tools]# service nginx status
nginx (pid  1633) is running...
[root@mail tools]# service dovecot status
dovecot (pid  1463) is running...
[root@mail tools]# service postfix status
master (pid 1598) is running...
[root@mail tools]# service mysqld status
mysqld (pid  1435) is running...
[root@mail tools]# service uwsgi status
uwsgi (pid  1650) is running...

I'm digging through as many logs as I can find, looking for any that respond with errors or that do not respond at all. Thanks for any and all direction.

Re: Sudden Loss of Connectivity and Responsiveness

If I installed 0.9.5-1 on a new VPS instance, then what mysql/data files would the new install require from my current instance (in order to keep accounts and their messages?) Is this scale of migration possible?

Re: Sudden Loss of Connectivity and Responsiveness

*) Is your IP address blocked in iptables on server? Try to stop both fail2ban and iptables services for testing.
*) Any related log in Postfix/Dovecot log files?

Yes!.. my IP address was being blocked! I used my mobile device (over 4G with an IP address from my carrier...) and sure enough!.. I am back to getting mail again!

I must of tripped up fail2ban when setting up and testing a new account in Thunderbird, this is quite a relief!

[root@mail /]# fail2ban-client set dovecot-iredmail unbanip my.ip.addr.here
my.ip.addr.here

And I have access again!.. I've got the iRedMail admin panel back and me and my team are syncing folders again! Thanks a ton Zhang, seriously!.. my weekend was looking frantic, but you really saved me, awesome support!
