Problem

Email notification do not work when special characters are saved at password field (angle brackets in my case)

Expected behavior

Special characters are processing properly

Actual behavior

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/motioneye/handlers.py", line 837, in test
    subject=subject, message=message, files=[])

Does your email server support hashed, tokenized, delimited or encrypted passwords?
"<" and ">" are disallowed characters in many systems and applications.

This is not my server, so I have no idea what kind of passwords it may support.
It is definitely support plain-text auth with special characters. And I cannot change the password.

You could try to edit the camera-X.conf file (X being the camera number)
sudo nano /etc/motioneye/camera-X.conf
Towards the end of the file should be a line beginning: on_event_start
Look for your password in that line (it is a VERY long line)
make sure your password shows as '<P@ssw0rd>'
(with the single quotes and your "<" & ">"as appropriate)
Save it, and trigger another email via motion.

Removed all special characters from password and got the same error when trying to send Test Email.

on_event_start /usr/lib/python2.7/site-packages/motioneye/scripts/relayevent.sh 
"/data/motioneye/motioneye.conf" start %t; 
/usr/bin/python /usr/lib/python2.7/site-packages/motioneye/meyectl.pyc sendmail -c /data/motioneye/motioneye.conf 
'smtp.xxxx.xxx' '25' '***accountname_here***' '***password_here***' 'False' 'hass@from.mail.com' 
'personal@gmail.com' 'motion_start' '%t' '%Y-%m-%dT%H:%M:%S' '0'

Weird, but looks like this problem is not related to special characters.

I thought you said "It is definitely support plain-text auth with special characters. And I cannot change the password."
It would have been helpful to mention how you were set up from the beginning.
Since it involves HA and their docker wrapper I must ask you to take that out of the equation.
Please install the motionEye version of docker:
https://github.com/ccrisan/motioneye/wiki/Install-In-Docker
and see if it occurs there.
