    I think that problem is that antivirus find an eml file in attachment and block message

    You could try sending a message without an EML attachment to see if it delivers successfully.

    Thank you.

    not is possible because PEC email servers build a message pre-formatted with eml attachment, but I see in returned message error:

    recipient@email.it
    This message has been rejected because it has
    a potentially executable attachment "postacert.eml"
    This form of attachment has been used by
    recent viruses or other malware.
    If you meant to send this file then please
    package it up as a zip file and resend it.


    I disabled in exim filter file the check on eml extensions, but I think that is a bad idea :-(

    Yes, the EML extension is not allowed by default. You are welcome to enable it, but keep in mind it's disabled due to the common occurrence of malicious emails which use that attachment.

    Thank you.
