A solution to this is to add your mailman host (which would typically 
be 127.0.0.1) into smtp_reserve_hosts and then set the related 
parameters such as smtp_accept_reserve, smtp_load_reserve and the 
various *_load* options so that incoming SMTP is always accepted from 
mailman (although the messages may be queued rather than immediately 
delivered).

The upside of this is that it puts less load on the system than 
additional invocations of exim from the command line, and all your load 
policy is pretty much in one place.  Whichever method you use there may 
still be errors caused due to (for example) running out of spool space.

[I'll try and work out a reasonable note on this for the mailman/exim 
howto information - alternatively I would just *love* it if someone 
would come up with some text for me :-) ]
