1. > |  | ### TMDA Pre-Configuration You may need to make some system-wide configuration changes to your MTA software depending on which one you are running. [ qmail | Postfix | Exim ] #### MTA Configuration (qmail) No changes need to be made to your qmail configuration in order to use TMDA. #### MTA Configuration (Postfix) Enable the recipient_delimiter parameter in Postfix's main.cf if it isn't already. The Postfix default is `+` but `-` is an acceptable value as well. Just make sure it matches RECIPIENT_DELIMITER in your tmdarc. #### MTA Configuration (Exim) Edit your Exim run time configuration file as follows: ##### MAIN CONFIGURATION TMDA uses sendmail's `-f' option to set the envelope sender address on outgoing messages. By default this option is only available to Exim's "trusted users". From the Exim Specification: "A trusted user is root or the Exim user or any user listed in the trusted_users configuration option, or any user for whom the currently set group is the Exim group (if defined) or whose current group or any supplementary group is one of those listed in the trusted_groups configuration option." It is recommended that you become a trusted-user, or else the client side of TMDA becomes much less functional. ##### DIRECTORS CONFIGURATION TMDA is heavily based on user "extension addresses" (e.g, username+extension@domain.dom), and your Exim must be able to understand them. It doesn't by default. Both `+` and `-` are an acceptable values for the suffix, just make sure it matches RECIPIENT_DELIMITER in your tmdarc. Add the following two lines to both the userforward and the localuser directors if they are not there already:
   >     suffix = -*     # or "+*" if you prefer "user+suffix" addresses
   >     suffix_optional
1. > ##### TRANSPORTS CONFIGURATION TMDA receives much of it's information about the envelope of an incoming message from environment variables set by the MTA. Most importantly, SENDER (the full envelope sender address), RECIPIENT (the full envelope recipient address), and EXT or EXTENSION (the recipient address extension). Exim currently sets only the first, so you must set the other two using the environment pipe option. Set environment as follows under the address_pipe transport:
   >     address_pipe:
   >       driver = pipe
   >       return_fail_output
   >       environment = EXTENSION=${sg{$local_part_suffix}{(^\\-|^\\+)}{}}:\
   >                     RECIPIENT=$local_part$local_part_suffix@$domain
