PowerMTA’s GDPR assistance feature

With the GDPR becoming enforceable next week, I thought it would be good to point out a feature we added to PowerMTA v4.5r13 last quarter. Designed together with our partner Postmastery, it allows you to very easily remove or protect, by way of a secure hash, PII normally stored in PowerMTA’s accounting files.  For example, to redact it, you’d configure:

<acct-file acct.csv>
    privacy-policy redact "redacted"
    ...
</acct-file>

Or…

<acct-file acct.csv>
    privacy-policy siphash "secret"
    ...
</acct-file>

to protect it with a hash. PowerMTA’s User’s Guide Section 11.3.1 has more details.

In this quarter’s v4.5r14, we’ll also be adding support for “negative” queue-filter patterns, allowing you to apply accounting file options such as these only to certain domains or Virtual MTAs:

<acct-file redacted.csv>
    queue-filter */vmta1
    privacy-policy redact "redacted"
    ...
</acct-file>

<acct-file notredacted.csv>
    queue-filter !*/vmta1, */*
    privacy-policy retain
    ...
</acct-file>

This way, the PII would be redacted from vmta1’s records, but not from any others.
