You could call exim without a -q option then run exim -qf on a cron job (thats completely dumb queue handling) Better would be to set up a retry rule for the specific error that you get to retry every minute for 5 days. NB this wont actually do a retry every minute, but it will do a retry every queue run. cf http://www.exim.org/exim-html-4.50/doc/html/spec_32.html#SECT32.3 > > Cheers, > > John. > > > -- > ## List details at http://www.exim.org/mailman/listinfo/exim-users > ## Exim details at http://www.exim.org/ > ## Please use the Wiki with this list - http://www.exim.org/eximwiki/ > -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
