Hello, updating aapanel will not affect the operation of the website mysql. aapanel is an independent service.
Is your mailbox server deployed by yourself?
Possible problem is

The address of Mail Host is different from the mail domain.
Is the SSL certificate of the mail server correctly deployed and does it include authentication Mail Host?

Hello, please check if your server can connect to port 25 of gmail? If not, maybe your server does not allow connections to port 25 of other servers.
If you cannot connect to port 25 of other servers, you cannot send emails.
CentOS:
yum install telnet -y && telnet gmail-smtp-in.l.google.com 25
debian/ubuntu:
apt install telnet -y && telnet gmail-smtp-in.l.google.com 25

Wow, thank you, it turns out that port 25 on my VPS has not been opened by the service provider, and now it is running well.
