Why my server can't receive any emails

[starsareintherose]

I use my gmail to send a email to the domain mail, there is no log related with it, it can't receive any emails.

My DNS

port seems okay

tcp6       0      0 :::465                  :::*                    LISTEN      930182/maddy

my config file

## Maddy Mail Server - default configuration file (2021-08-16)
# Suitable for small-scale deployments. Uses its own format for local users DB,
# should be managed via maddyctl utility.
#
# See tutorials at https://maddy.email for guidance on typical
# configuration changes.
#
# See manual pages (also available at https://maddy.email) for reference
# documentation.

# Local storage & authentication

# pass_table provides local hashed passwords storage for authentication of
# users. It can be configured to use any "table" module, in default
# configuration a table in SQLite DB is used.
# Table can be replaced to use e.g. a file for passwords. Or pass_table module
# can be replaced altogether to use some external source of credentials (e.g.
# PAM, /etc/shadow file).
#
# If table module supports it (sql_table does) - credentials can be managed
# using 'maddyctl creds' command.

    table sql_table {
        driver sqlite3
        dsn credentials.db

}

# imapsql module stores all indexes and metadata necessary for IMAP using a
# relational database. It is used by IMAP endpoint for mailbox access and
# also by SMTP & Submission endpoints for delivery of local messages.
#
# IMAP accounts, mailboxes and all message metadata can be inspected using
# imap-* subcommands of maddyctl utility.
