The first time I tried to send archived files to/from a Gmail email account was 1 month ago and I noticed that you cannot send this kind of files. I tried multiple times and failed always.

If I send an email to a Gmail account, I get a reply with the text message:

> This is an automatically generated Delivery Status Notification.
> 
> Delivery to the following recipients failed.
> 
> anemailaddress@gmail.com

Viewing the email source, I found out this:

> Final-Recipient: rfc822;anemailaddress@gmail.com Action: failed  
> Status: 5.5.0 Diagnostic-Code: smtp;552-5.7.0 This message was blocked

**Is there a way to circumvent this?** The archived files I tried were zip, rar, no password, with password, encrypted. None of them worked. The archive contained a Kicad project.
