Hi,

Create a data record in xml. But it will be better to exclude user id and password from it.

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data noupdate="1">
        <!--        For Outgoing Mail server-->
        <record id="out_going_mailserver_data" model="ir.mail_server">
            <field name="name">Description</field>
            <field name="sequence">Priority</field>
            <field name="smtp_host">SMTP Server</field>
            <field name="smtp_port">SMTP Port</field>
            <field name="smtp_encryption">Connection Security</field>
            <field name="smtp_user">Username</field>
            <field name="smtp_debug">Debugging</field>
            <field name="smtp_pass">Password</field>
        </record>
        <!--        For Incoming mail server-->
        <record id="in_coming_mailserver_data" model="ir.mail_server">
            <field name="name">Name</field>
            <field name="type">Type</field>
            <field name="server">Server Name</field>
            <field name="port">Port</field>
            <field name="is_ssl">SSL/TLS</field>
            <field name="user">Username</field>
            <field name="password">Password</field>
            <field name="object_id">Create a New Record</field>
            <field name="priority">Server Priority</field>
            <field name="attach">Keep Attachments</field>
            <field name="original">Keep Original</field>
            <field name="active">Active</field>
        </record>
    </data>
</odoo>
