bounceHammer have been downloaded and used by many users and companies since the first release on March 2010 and has been EOL: End Of Life on February 29, 2016. Thanks for using bounceHammer for a long time. We are now providing Sisimai (the successor of bounceHammer, more faster, more higher precision of analysis) as a bounce mail parser library in BSD 2-Clause License.
bounceHammer's WebUI/Mastertables is for refering and editing the contents of the following mastertables: Addresser (sender's email address), SenderDomain (the domain part of Addresser), Destination (the domain part of recipient's email address), Reason (of email bounce), HostGroup (grouped by destination), and Provider (more detailed of HostGroup).
Some mastertables can be turned on "Read Only" mode from the operations on WebUI only by editing etc/webui.cf. If many users can access bounceHammer/WebUI, you may turn on "Read Only" mode for avoiding destruction of the records on the database.
The mastertables which are turned on "Read Only" mode are not updated and deleted from WebUI only. But "Read Only" mode is not affected by the operation of the command line tool (bin/tablectl command).
bin/tablectl command has the same function.
