If you are using Direct LDAP lookups instead of Dirsync then you can also set this variable to a value that maps to a memory mapped file system, like /tmp/. The location must exist prior to starting up the MTA, i.e. the MTA will not create this directory if it is not present. I often use simply /tmp/.Please note that this can not be set to the same location as Section 6.3
Set this parameter to a value that maps to a memory mapped file system, like /tmp/. Channels such as the conversion channel place files in this directory. The location must exist prior to starting up the MTA, i.e. the MTA will not create this directory if it is not present. I often use simply /tmp/. Please note that this can not be set to the same location as Section 6.3
If you wish, you can set the IMTA_TCP_FLAG_RETENTION option in your imta_tailor file to, say 1, so that the old *.data-failed files get purged after a day. You can find these files in msg-<instance>/imta/ queue/<channel-name>/spool/. Note -- this directory will only exist if the MTA needed to write files to this directory. Many sites will never see this directory on their systems.
