I'm zipping up a rather small folder, 243KB, containing Visual Studio project and solution files using 7zip or the Windows built-in Compressed (zipped folder) from the right click menu.
I've tried using Gmail, Outlook and Yahoo mail but none of them send my email with attachment.
Gmail does not show any error and the recipient confirms they never receive any email. Email without attachment is received successfully.
Outlook shows delivery failed email in my inbox, Yahoo also shows mailer-demon error in my inbox.
I do not want to use Google Drive or Microsoft Onedrive.
My question is how do I send email with zipped attachments?
