Still worth, as I have tried this address in a telnet session:
        EHLO mail.test.com
        250-mail.domain.com
        250-PIPELINING
        250-SIZE 10240000
        250-VRFY
        250-ETRN
        250-STARTTLS
        250-ENHANCEDSTATUSCODES
        250-8BITMIME
        250 DSN
        MAIL FROM: &_1;@mailing.leadsponsorises.com
        501 5.1.7 Bad sender address syntax
        
Why was this email accepted this afternoon?

Cheers,
Julien
