The DSN status is set to 5.3.4 (see
RFC1893).
This delivery agent equate is usually used with UUCP agents, where the cost of telephone
connections is of concern. It can also prove useful in mail to files, where disk space is
limited.
20.5.8.1 Modify M= using an mc configuration macro
Using V8 sendmail??™s mc configuration technique, the maximum message size can be
changed by defining an appropriate macro. The following, for example, is one way to
increase the limit on UUCP traffic to a more reasonable figure of one million:
define(`UUCP_MAILER_MAX?? `1000000??) ?†? this must be
MAILER(`uucp??) ?†? before this
See the section describing a particular delivery agent to find an appropriate mc macro with
which to redefine the M= for that delivery agent. See Table 20-1 on page 717 for a guide to
all delivery agents.

20.5 Delivery Agent Equates | 747
To change the limit for agents that lack a definition, copy an existing delivery agent definition,
and then modify it as outlined in ?§20.3.2 on page 715.
20.5.9 m=
Max messages per connection V8.10 and later
The m= delivery agent equate is used to limit the number of envelopes that can be delivered
during any single SMTP or LMTP connection.* This can prove useful because more and
more sites on the Internet have started rejecting envelopes after too many have been sent.
