How to catch error while sending an email with an hybrid code batch and powershell ?

[Hackoo]

Hi
I'm working for a script to send an e-mail with SSL Authentification (Gmail) with an hybrid code Batch and Powershell Script !
So my question how can i catch the error in order to show the correct message.
Thank you !

<# : Batch portion
@rem # The previous line does nothing in Batch, but begins a multiline comment block
@rem # in PowerShell.  This allows a single script to be executed by both interpreters.
@echo off & Mode 100,5 & color 0A

echo(
rem # This a Powershell command executes the hybrid portion at the bottom of this script
for /f "delims=" %%I in ('powershell -noprofile "iex (${%~f0}|out-string)"') do set "%%I"
exit /b
rem # End multi-line PowerShell comment block.  Begin PowerShell scripting.
: end Batch / begin PowerShell hybrid code #>

Hi
I think that i got it here the working code, all the comments are welcome for improving this script
For whom want to test this hybrid code, just copy and save this piece of code as Gmail_Batch_PS_Sender.bat
So, when you execute it, the script asked you to type your Gmail Account without "@gmail.com" and its password for sending emails, just all

Gmail users can access their account on the official website or by using first-party or third-party apps and services instead. A first party app is for instance Google's official Gmail app for Android, while Thunderbird and the mail client app of Windows 8 are third-party apps.

Google announced back in April 2014 that it would improve the sign-in security of its services and affect any application sending usernames and passwords to the company.

The company suggested to switch to OAuth 2.0 back then but did not enforce it up until now.

If you open the new less secure apps page under security settings on Google, you will notice that Google has disabled access by default.

Note: You see the page only if you are not using Google Apps or have enabled two-factor authentication for the account.

You can flip the switch here to enable less secure applications again so that access is regained.
