The methods used and
the circumstances required to trigger conversion are described under the EightBitMode
option (?§24.9.45 on page 1025).
Defining MIME8TO7 to a value of 1 causes support for conversion to be included in sendmail.
It is defined as 1 by default. To disable the inclusion of conversion code, add a line
like the following to your Build m4 file:
APPENDDEF(`confENVDEF??, `-DMIME8TO7=0??)
?†‘
exclude support
One side effect of defining MIME8TO7 to 0 is that it causes all MIME support to also be
excluded. Unless you have a compelling reason to do otherwise, we recommend that
MIME8TO7 remain enabled.
If you are running a precompiled sendmail binary, you can use the -d0.1 debugging
command-line switch (?§15.7.1 on page 542) to determine whether MIME8TO7 support is
included (if it appears in the list, support is included).
3.4.27 NAMED_BIND
Support DNS name resolution Tune with confENVDEF
The sendmail program automatically takes advantage of DNS lookups or MX records to
resolve addresses and canonical hostnames. If your site is a UUCP-only site (or is otherwise
not connected to the Internet) and does not run named(8) locally, you should
probably disable NAMED_BIND:
APPENDDEF(`confENVDEF??, `-DNAMED_BIND=0??)
?†‘
disable DNS lookups
If you are running a precompiled sendmail binary, you can use the -d0.1 debugging
command-line switch (?§15.
