I need Allow " BAD-HEADER-0 " in incoming mails

[insulae]

my server is blocking mails with the legend:

vps amavis[19243]: (19243-20) Blocked BAD-HEADER-0 {BouncedOpenRelay,Quarantined}

I need to receive these emails, is there a way to allow these emails?
(The incoming mails are not from a server that I can manage so I cannot "fix" the headers)

Thanks!
