I need to add the IGNORE_SMTP_LINE_LENGTH_LIMIT macro to my Exim, but I
don't know which is the configuration file where I have to write it and
I don't know the correct syntax.
I've already tried appending
IGNORE_SMTP_LINE_LENGTH_LIMIT='1'
to /etc/exim4/update-exim4.conf.conf
and then running
# update-exim4.conf
but it replies
undocumented line IGNORE_SMTP_LINE_LENGTH_LIMIT=1 found in
/etc/exim4/update-exim4.conf.conf, generating exim macro
and that does not sound good to me. What's the correct way to specify a
macro (that one or others) in the Exim configuration?
