Seafile can`t send notifications via email

Hello there again.
I installed Seafile CE 6.1.2 and all works fine except sending users notifications/reset passwords,etc.
I tried many variants of changing seahub_settings.py but no one works.
Here is example one of my test settings:
EMAIL_USE_TLS = True
EMAIL_HOST = ‘mail.domain.com’ # smpt server
EMAIL_HOST_USER = ‘mail’ # username and domain
EMAIL_HOST_PASSWORD = ‘password’ # password
EMAIL_PORT = 587
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER
SERVER_EMAIL = EMAIL_HOST_USER
Also i tried to disable using TLS and changing port(for 465/25) but result was the same.
seahub.log seems like:
2017-09-08 15:11:00,510 [ERROR] seahub.views.sysadmin:1000 user_reset SMTP AUTH extension not supported by server.
That message i see even when try config without using SSL/TLS and even with Google mail account.
Can anyone say me what`s wrong?
Thank you.

Same issue,debian edition pro 6.2.4.

But it’ll work if the sent mail is a register,ignoring the head of mail is:
Account activation on 127.0.0.1:8000.

Without any configuration change,it just don’t show like:
Account activation on seafile.mydomail.com.

But in the version of 6.1.9 pro,it can send me a normal thing like above.

Seafile,in love you and bothered by you too…
