Betreff: [exim] Other IP checking than SPF
Hi list,

     appologies that this isnt specifically Exim related, however Im having the following problem from a customer attempting to relay email via our Exim servers:


We are getting an


    SMTP error from remote mail server after MAIL FROM:<hello@???>
SIZE=1892:
    host mail.itcuk.net [195.226.40.68]: 550 Sorry, <hello@???> is
not allowed access from your location


So it seems the remote host is doing some check that we are genuinely sending for the domain, however there is no SPF record for the domain. Does anyone know what other methods of checking the senders IP address could be causing the issue?


thanks for any clues! Andy.From renaud/exim-users/lists.exim.org/utyaepsn@??? Mon May 12 17:12:54 2008
