[pfx] Re: [pfx-ann] SMTP Smuggling, workarounds and fix

Hi
A good idea in my opinion,  additionally add 
reject_sender_login_mismatch with maps (u...@domain.ltd user@domainltd)

smtpd_sender_restrictions =
    ...
    reject_sender_login_mismatch,
    ...
    reject_unauth_pipelining,


Than only reject_unauth_pipelining
smtpd_data_restrictions = reject_unauth_pipelining

in postfix3.4.x ?
