the email address is corect? or not?

 

[SoftwareRT]

Based on the API response, the email gss.italy@iol.it is not fully valid for delivery.

A quick breakdown ---

1. syntax_valid: true -- The email format is syntactically correct.
2. is_disposable: false -- The email is not from a disposable email service.
3. is_deliverable: false -- The email is not deliverable (the server likely failed to verify its existence).
4. can_connect_smtp: false -- The server could not establish an SMTP connection to confirm the mailbox's existence.
5. mx_records: true -- The domain iol.it has valid MX (Mail Exchange) records, meaning the domain can receive emails.
6. score: 0.48 -- The score (likely a confidence score) is below a typical threshold (e.g., 0.8 or higher for reliable validity).

This is not a vb6 question. This is a question about a proprietary REST API. What does the API documentations say?

>could not establish an SMTP connection to confirm the mailbox's existence
SMTP has no real capability confirm or deny existence of a mailbox (at best it can provide a somewhat vague idea of whether a mailbox is 'unavailable' or not on a particular server). Yes, there are extended/enhanced response codes that can indicate more detailed information about a target mailbox but they are not mandatory

This makes me treat this mailbox validation service (at least the SMTP element) with scepticism - I personally wouldn't rely on the result, I'm afraid
