update mail/dovecot2-pigeonhole to 0.4.17
Changelog v0.4.17:
- LDA Sieve plugin: Fixed handling of an early explicit keep during multiscript execution. Action side-effects and the message snapshot would be lost at the final stage where the implicit keep is evaluated. This could result in the IMAP flags assigned to the message to be forgotten or that headers modified by the "editheader" extension would revert to their original state.
- file script storage: Amended the up-to-date time stamp comparison for on-disk binaries to include nanoseconds. This will fix problems occurring when both binary and script are saved within the same second. This fix is ineffective on older systems that have no support for nanoseconds in stat() timestamps, which should be pretty rare nowadays.
- file script storage: Improve saving and listing permission error to include more details.
- imapsieve plugin: Make sure "INBOX" is upper case in static mailbox rules. Otherwise, the mailbox name would never match, since matching is performed case-sensitively and Dovecot only returns the upper-cased "INBOX".
- imapsieve plugin: Fixed assert failure occurring when used with virtual mailboxes.
- doveadm sieve plugin: Fixed crash when setting Sieve script via attribute's string value.
