I'm offering here, for anyone interested, my patched version of
sendmail/rmail (version V1.17-beta.31{ask@castrov.UUCP/10} Aug 07 1994).
The main motivation for the changes was to comply with the strong
"SmartUUCP" requirements of my local domain. These requirements go
beyond the initial "SmartUUCP" implementation in sendmail 1.17.31.
At the same time a few other enhancements were made. A new concept
in config variables is introduced. "Host-specific" variables are
of the form "Host-xxx-variable". They are used in in preference
of the ordinary "host-non-specific" variables when doing work for
the system specified in "xxx". Sendmail uses two host-specific
variables: Host-xxx-SmartUUCP and Host-xxx-MaxRMailLen.
Changes:
--------
* When sending a message to a "SmartUUCP" neighbor, generate the Envelope
"rmail " addresses in @-format rather than !-format. This is required
by some "SmartUUCP" sites.
* Support per-host config variables for the SmartUUCP flag of the form
Host-xxx-SmartUUCP, where xxx is the neighbor. Translate messages to
and from "SmartUUCP"-format, so we can act as a bridge between the often
incompatible worlds.
* Support per-host config variables for the MaxRMailLen value of the form
Host-xxx-MaxRMailLen, where xxx is the neighbor. Each neighbor can have
a value tuned to their limitations rather than being restricted to the
smallest value of all neighbors.
* Be more efficient about packing addressess onto the rmail line. We used
to send off messages to *all* neighbors as soon as the accumulation of
addresses for *one* neighbor was full.
* Tell UUX if we are running as "postmaster". This will appear in the
remote system's uulib:logfile.
* Record the SUBVERSION in the Received: line, for easier reporting of bugs.
