class Net::IMAP::Envelope
Net::IMAP::Envelope
represents envelope structures of messages.
- Note
-
When the
sender
andreply_to
fields are absent or empty, they will return the same value asfrom
. Also, fields may return values that are invalid for well-formed [RFC5322] messages when the message is malformed or a draft message.
See [IMAP4rev1 §7.4.2] and [IMAP4rev2 §7.5.2] for full description of the envelope fields, and Message envelope and body structure at Net::IMAP
for other relevant RFCs.
