Oh I said that there were another name…
I think it won’t be a problem if the mailsafe feature works only with attachments, isn’t it? You can have a spam killer that block unwanted emails or, at least, prevent their downloading without your permission (like Spamihilator). You can be informed of the presence of a specific email and then download it or delete it in the server (without downloading). 
Btw, I use ZA for years and works great with avast! ;D
