exim_checkaccess IP-address email@address [more Exim options]
Exim's -bh command line argument allows you to run a fake SMTP session
with debugging output, in order to check what Exim is doing when it is
applying policy controls to incoming SMTP mail. However, not everybody
is sufficiently familiar with the SMTP protocol to be able to make full
use of -bh, and sometimes you just want to answer the question "Does
this address have access?" without bothering with any further details.
The exim_checkaccess utility is a 'packaged' version of -bh. It takes
two arguments, an IP address and an email address:
exim_checkaccess 10.9.8.7 A.User@a.domain.example
The utility runs a call to Exim with the -bh option, to test whether
the given email address would be accepted in a RCPT command in a TCP/IP
connection from the host with the given IP address. The output of the
utility is either the word 'accepted', or the SMTP error response, for
550 Relay not permitted
When running this test, the utility uses "<>" as the envelope sender
address for the MAIL command, but you can change this by providing
additional options. These are passed directly to the Exim command.
For example, to specify that the test is to be run with the sender
address "email@example.com" you can use:
exim_checkaccess 10.9.8.7 A.User@a.domain.example \
Note that these additional Exim command line items must be given after
the two mandatory arguments.
This manual page needs a major re-work. If somebody knows better groff
than us and has more experience in writing manual pages, any patches
would be greatly appreciated.
