Good afternoon,

I am having problems sending emails.

Could you help me?

I have already tried installing a new certificate and the ports are all OK.

The log errors are as follows:

[2026-01-06 18:47:51][DEBUG] - unzip -o panel.zip -d /www/server/ && chmod 700 /www/server/panel/BT-Panel

networkInfo['simple_system'] = networkInfo['system'].split(' ')[0] + ' ' + re.search('\d+', networkInfo['system']).group()
DEPRECATION: Loading egg at /www/server/panel/pyenv/lib/python3.12/site-packages/PyMySQL-0.9.3-py3.12.egg is deprecated. pip 24.3 will enforce this behaviour change. A possible replacement is to use pip for package installation.. Discussion can be found at https://github.com/pypa/pip/issues/12330
