class Net::IMAP::Envelope

Net::IMAP::Envelope represents envelope structures of messages.

Note

When the sender and reply_to fields are absent or empty, they will return the same value as from. 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.

Public Instance Methods

bcc → array of Net::IMAP::Address click to toggle source

Returns an array of Address that represents the Bcc header.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 653
cc → array of Net::IMAP::Address click to toggle source

Returns an array of Address that represents the Cc header.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 647
date → string click to toggle source

Returns a string that represents the Date header.

Note

For a well-formed [RFC5322] message, the date field must not be nil. However it can be nil for a malformed or draft message.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 577
from → array of Net::IMAP::Address or nil click to toggle source

Returns an array of Address that represents the From header.

If the From header is absent, or is present but empty, the server returns nil for this envelope field.

Note

For a well-formed [RFC5322] message, the from field must not be nil. However it can be nil for a malformed or draft message.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 600
in_reply_to → string click to toggle source

Returns a string that represents the In-Reply-To header.

Note

For a well-formed [RFC5322] message, the in_reply_to field, if present, must not be empty. But it can still return an empty string for malformed messages.

Servers should return nil when the header is absent and an empty string when it is present but empty. Some servers may return a nil envelope member in the “present but empty” case. Clients should treat nil and empty string as identical.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 659
message_id → string click to toggle source

Returns a string that represents the Message-ID.

Note

For a well-formed [RFC5322] message, the message_id field, if present, must not be empty. But it can still return an empty string for malformed messages.

Servers should return nil when the header is absent and an empty string when it is present but empty. Some servers may return a nil envelope member in the “present but empty” case. Clients should treat nil and empty string as identical.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 675
reply_to → array of Net::IMAP::Address or nil click to toggle source

Returns an array of Address that represents the Reply-To header.

Note

If the Reply-To header is absent, or is present but empty, the server sets this field to be the same value as from. Therefore, in a well-formed [RFC5322] message, the reply_to envelope field must not be nil. However it can be nil for a malformed or draft message.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 627
sender → array of Net::IMAP::Address or nil click to toggle source

Returns an array of Address that represents the Sender header.

Note

If the Sender header is absent, or is present but empty, the server sets this field to be the same value as from. Therefore, in a well-formed [RFC5322] message, the sender envelope field must not be nil. However it can be nil for a malformed or draft message.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 614
subject → string or nil click to toggle source

Returns a string that represents the Subject header, if it is present.

Note

Servers should return nil when the header is absent and an empty string when it is present but empty. Some servers may return a nil envelope member in the “present but empty” case. Clients should treat nil and empty string as identical.

# File net-imap-0.4.16/lib/net/imap/response_data.rb, line 588
to → array of Net::IMAP::Address click to toggle source

Returns an array of Address that represents the To header.
