I am using macros but none that start with an underbar '_'. I have one that defines the configuration directory. CFG_DIR = /etc/exim I then use that throughout the configuration file. Aside from adding the "keep_environment =" line to exim.conf no other changes were made to my configuration between 4.66 and 4.88. I can try expanding the simple macro above manually in my configuration just to see if that causes the problem to go away. I can also sanitize the configuration and post it here if you think that would help. > > > If I changed from piping the message to EXIM to connecting to > > localhost:25 and sending the message via SMTP would that remove calls to > > readconf_main. > > It would remove the per-message reception startup configuration read. > The delivery cost would still be there. > > -- > Cheers, > Jeremy > Thank you for the reply.
