Lately we've seen that there were lots of reports about email problem with Rainloop.
In CyberPanel version v1.8.5 and above we are using CRYPT format for email passwords. Which requires an upgrade in the Dovecot version.
Dovecot was upgraded in the upgrade process but due to plugin priorities upgrade did not went through for some users.
We've taken care of this issue in the upgrade and install process for future, however you can manually solve this issue by running this commands:
yum remove yum-plugin-priorities -y
and set enabled to 0.
name=Dovecot 2.3 CentOS $releasever - $basearch
Finally upgrade dovecot
yum makecache -y
yum update -y
In case you can't get into Rainloop, try changing password for your emails.
These days we've received countless tickets and Facebook messages due to which we could not react in timely manner for all queries.
In case your issue is still not resolved you can reach us via helpdesk/forums. For bug reports do not use our Facebook group or live chat.
Sorry for any inconvenience caused.
