Directory location MTA options
As of Messaging Server 7.0-0.04, many formerly configurable (via MTA Tailor option) MTA directory locations are now hard-coded. But
tmpdir (replacing the former
imta_tmp MTA Tailor option) and
langdir (replacing the former
imta_lang MTA Tailor option) are still configurable; (note that in legacy configuration, these two options are MTA option file options).
