Gromox 2.15

Fixes:

• imap: do not emit continuation request on LITERAL+ (now also for large literals >64K)
• exmdb: ignore softdeleted folders when validating new folder name
• exmdb: explicitly rollback SQLite transactions when the commit operation failed, to resolve cases of cannot start a transaction within a transaction
• exmdb: ACE entries for anonymous were misreported to clients

Enhancements:

• delivery: support for plus-addresses/recipient delimiters, e.g. <user+extension@example.com>
• delivery: new config directive lda_recipient_delimiters
• mbop: new subcommand recalc-size to recalculate store size

Changes:

• alias_resolve: config directives are no longer read from /etc/gromox/alias_resolve.cfg but now from /etc/gromox/gromox.cfg
• oxcmail: do not emit Content-Disposition creation-time/modification-time parameters when those fields are not present in the MAPI object
• Delete unused columns and indexes from the associations MariaDB table; (grommunio-admin-api should be updated to >= 1.12)
