MIME8TO7
Support MIME 8- to 7-bit conversion Tune with confENVDEF
V8 sendmail contains the internal
ability to convert 8-bit MIME message content into
7-bit MIME so that mail can be transported through
non-8-bit gateways. The methods used and the
circumstances required to trigger conversion are
described under the EightBitMode
option (EightBitMode 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 (-d0.1 on page 542) to determine whether MIME8TO7
support is included (if it appears in the list,
support is included).
