source: subversion/branches/devel-api/program/steps/mail/sendmail.inc @ 2336

Last change on this file since 2336 was 2336, checked in by ziba, 4 years ago

Added an array of required plugins rcube_plugin_api.php. It's got room to grow.
New core plugin: filesystem_attachments - the existing disk based attachment handling now in plugin form (with one garbage collection bug fix)
New plugin: database_attachments - multi-server safe, database backed attachment temp file handling
New plugin hooks: remove_attachment, display_attachment, upload_attachment, save_attachment, cleanup_attachments, get_attachment
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
