Hi list,
Yesterday I was informed by Users, that they can't send e-mails to one
of the banking institutions (so it's a little 'urgent' in businesses
manner).
The mails are rejected by Messagelabs / Symantec Cloud System, but do
not provide any relevant information:

I've already sent e-mails to postmas...@bankdomain.com, but not sure if
anyone is going to answer it..
Do you have any ideas / online tools so I could check my MTA configuration ?
BTW: The reverse DNS and SPF record are set correctly
Best regards,
