$_ignoreAttachments : boolean
Flag to ignore parts that EAS considers attachments.
Recursive iterator for Horde_Mime_Part objects. This iterator is self-contained and independent of all other iterators. Adapted from Horde_Mime package. Changed to allow what EAS would consider attachments to be ignored during iteration and to always include the base part.
_allowRecursion(\Horde_Mime_Part $part) : boolean
Return whether or not to allow recursion into a mime part when iterating all of the parts. So far, only disallows this for message/rfc822 parts to prevent each mime part of the rfc822 part to display as an attachment.
The part to check.
True is we can descend into the part. False otherwise.
