Solution to "authentication failed" error in Rainloop

Hi all if you face errors with logging in to Rainloop and if your logs have something as "Invalid password in passdb: crypt() failed: Invalid argument" Then there is a simple fix for this. You need to update your Dovecot to 2.3.x as bcrypt is supported by 2.3.x. The steps are as follows:
1) Add the reposity key of dovecot to the rpm key store:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 18A348AEED409DA1

2) Add the official dovecot Ubuntu Repo to sources.list

(this example is for Ubuntu 18)

sudo nano /etc/apt/sources.list.d/dovecot.list

insert into:

deb [arch=amd64] https://repo.dovecot.org/ce-2.3-latest/ubuntu/bionic bionic main

Save it and close editor

3) Do a:

sudo apt update

4) Do a:

sudo apt dist-upgrade

5) Reboot your machine.

you rainloop should work nicely now.
