EXINEXT(8)                                                    System Manager's Manual                                                   EXINEXT(8)

NAME

       exinext - Finding individual retry times

SYNOPSIS

       exinext address|message-id

DESCRIPTION

       A  utility called exinext (mostly a Perl script) provides the ability to fish specific information out of the retry database.  Given a mail
       domain (or a complete address), it looks up the hosts for that domain, and outputs any retry information for the hosts or for  the  domain.
       At present, the retry information is obtained by running exim_dumpdb (see below) and processing the output.  For example:

         exinext piglet@milne.fict.example
         kanga.milne.fict.example:192.168.8.1 error 146: Connection refused
           first failed: 21-Feb-1996 14:57:34
           last tried:   21-Feb-1996 14:57:34
           next try at:  21-Feb-1996 15:02:34
         roo.milne.fict.example:192.168.8.3 error 146: Connection refused
           first failed: 20-Jan-1996 13:12:08
           last tried:   21-Feb-1996 11:42:03
           next try at:  21-Feb-1996 19:42:03
           past final cutoff time

       You  can  also  give  exinext  a  local  part, without a domain, and it will give any retry information for that local part in your default
       domain.  A message id can be used to obtain retry information pertaining to a specific message.   This  exists  only  when  an  attempt  to
       deliver a message to a remote host suffers a message-specific error (see section 42.2).  exinext is not particularly efficient, but then it
       isn't expected to be run very often.
