With the -d flag, that part still doesn't change. All one gets with the -d flag is lots of file descriptors opening and closing. The only thing the log seems to show is that the authentication process goes wrong instantly but no clue whether or what causes that. I have looked in the man page and the word smarthost doesn't appear. /usr/share/doc/exim4-base/ has nothing with one file briefly mentioning a smarthost but no best practices or sample configuration examples. I also know experimentally that no part of /etc/exim4/passwd.client appears in the /var/lib/exim4/config.autogenerated file so exim4 must give that out on demand or maybe I should say it is part of the output generated during the session. Either the passwd.client file needs something else or another file needs modification as the user name and password are known to be good. The experiment was to generate a new conf.autogenerated file after modifying passwd.client and using diff between it and the previous config.autogenerated file. They were a perfect match. If there is a document somewhere describing this setup for exim4.80 or above, it should be useful as the changes apparently took place around version 4.79 or 4.80 and this version is 4.89. The fact that you are reading this message is proof that the user ID and password still work with smtp.suddenlink.net, just not in exim4 yet. Thank you. Martin McCormick
