<>In exim manual at 38.21:
. . .
For a sender callout check, Exim makes SMTP connections to the remote
hosts, to test whether a bounce message could be delivered to the sender
address. The following SMTP commands are sent:
HELO </primary host name/>
MAIL FROM:<>
RCPT TO:</the address to be tested/>
QUIT
. . .
From some mail server we obtain:
2005-02-08 11:12:55 H=(host.remote_domain.local) [213.183.154.54]:30396
I=[212.210.229.6]:25 sender verify fail for <aaaa@remote_domain.com>:
response to "MAIL FROM:<>" from mail.remote_domain.com [83.103.57.67] was: 550 Sorry, this server is configured to refuse this sort of mail
to combat the SPAM problem)
2005-02-08 11:12:55 H=(srvposta.remote_domain.local) [213.183.154.54]:30396 I=[212.210.229.6]:25 F=<aaaa@remote_domain.com> rejected RCPT <bbbb@local_domain.it>: Sender verify failed
Is it possible change:
MAIL FROM: <>
to
MAIL FROM: postmaster@local_domain.it
best regards
