      Hi all,
         
           I have received a complaint from a customer thats sit on our server(postconf  down below ) about not receiving a message from a particular sender  domain  " @... " since it was unable to receive the mail , my customer did supply an alternate address ( not managed by us ) with the message and this sort of  evidence ( wich does not include the header so it is basically useless ) :

       the mx responsible for this domain is mx.191.biz ( Telecom Italia - God save us all ) I checked my server logs for any evidence of this

      grep mx.191.biz /var/log/maillog* and this is the output :

      /var/log/maillog.1:Nov 27 12:42:22 darkstar postfix/smtp[2032]: D43C1214A4: to=<roberto.pucci@...>, relay=mx.191.biz[77.238.27.187]:25, delay=3.1, delays=0.01/0.03/0.79/2.3, dsn=2.0.0, status=sent (250 ok:  Message 215728826 accepted)

          So it seems that although my server do play nice with this server , there is no communication for those particular e-mails , unfortuntely neither olmar.191.it or 191.it ( both serverd by mx.191.biz )  do  comply with RFC RFC822, RFC1123 , e RFC2821 ( doesn't have either postmaster or abuse ) so I m stuck to try and contact a pratically non-existent helpdesk.

          So what I'd like to know is ... am I failing to see something obvious ( wich actually happens often ;-P ) ? or am right to believe the problem lies in the remote MTA or directly on the sender part ?
