SMTP authentication issue 535 when different smpt port is provided

[vishnu-narayanan]

Describe the bug

Chatwoot fails to send an email when the default SMTP port is changed from 587 to 25.

To Reproduce

Steps to reproduce the behavior:

1. Deploy chatwoot using helm charts
2. Change the SMTP related variables to the following

SMTP_ADDRESS="xxxxxxxx"
SMTP_PORT="25"
SMTP_USERNAME=""
SMTP_PASSWORD=""
SMTP_AUTHENTICATION= plain
SMTP_ENABLE_STARTTLS_AUTO= true
SMTP_OPENSSL_VERIFY_MODE= none

The username and password are expected to be empty here and should work as this config is working on other applications.

4. Try to send a password reset email.
5. See error

Net::SMTPAuthenticationError: 535 5.7.0 authentication failed

Expected behavior

Email should be sent.

@aswindevps Could you please take a look? cc: @pranavrajs

@dragma Could you try to update the deployment by removing SMTP_USERNAME, SMTP_PASSWORD and SMTP_AUTHENTICATION variables and see if that helps?
