List-ID header is added for broadcast lists.
UTF-8 in email headers is allowed only if
all recipient MTAs support SMTPUTF8 extension,
which is not always the case even if our submission service
reports SMTPUTF8 support.
feat: Make broadcast lists create their own chat - UIs need to ask for
the name when creating broadcast lists now (see
https://github.com/deltachat/deltachat-android/pull/2653)
That's quite a minimal approach: Add a List-ID header to outgoing
broadcast lists, so that the receiving Delta Chat shows them as a
separate chat, as talked about with @r10s and @hpk42.
Done:
- [x] Fix an existing bug that the chat name isn't updated when the
broadcast/mailing list name changes (I already started this locally)
To be done in other PRs:
- [ ] Right now the receiving side shows "Mailing list" in the subtitle
of such a chat, it would be nicer if it showed "Broadcast list" (or
alternatively, rename "Broadcast list" to "Mailing list", too)
- [ ] The UIs should probably ask for a name before creating the
broadcast list, since it will actually be sent over the wire. (Android
PR: https://github.com/deltachat/deltachat-android/pull/2653)
Fixes https://github.com/deltachat/deltachat-core-rust/issues/4597
BREAKING CHANGE: This means that UIs need to ask for the name when creating a broadcast list, similar to https://github.com/deltachat/deltachat-android/pull/2653.
This is needed to test periodic re-gossiping in existing chats.
Also add a test for verified groups on that even if "member added" message is missed by a device of
newly added member, after re-gossiping Autocrypt keys to the group it successfully learns these keys
and marks other members as verified.
Add protected-headers="v1" directive to Content-Type of an encrypted/signed MIME so that other MUAs
like Thunderbird display the true message Subject instead of "...".
This is an RFC 2045 requirement for base64-encoded MIME parts.
Previously referenced RFC 5322 requirement
is a general Internet Message Format requirement
and is more generous.
It can be used e.g. as a default in the file saving dialog. Also display the original filename in
the message info. For these purposes add Param::Filename in addition to Param::File and use it as an
attachment filename in sent emails.
Webxdc update messages may contain
long lines that get hard-wrapped
and may corrupt JSON if the message
is not encrypted.
base64-encode the update part
to avoid hard wrapping.
This is not necessary for encrypted
messages, but does not introduce
size overhead as OpenPGP messages
are compressed.
This commit adds new stock strings
"I added member ...",
"I removed member ..." and
"I left the group" that are sent over the network
and are visible in classic MUAs like Thunderbird.
Member name in these messages uses authname
instead of the display name,
so the name set locally does not get leaked when
a member is added or removed.
Message.set_text() and Message.get_text() are modified accordingly
to accept String and return String.
Messages which previously contained None text
are now represented as messages with empty text.
Use Message.set_text("".to_string())
instead of Message.set_text(None).
Moved custom ToSql trait including Send + Sync from lib.rs to sql.rs.
Replaced most params! and paramsv! macro usage with tuples.
Replaced paramsv! and params_iterv! with params_slice!,
because there is no need to construct a vector.
Recommended file size is used for recoding media.
For the upper size, we rely on the provider to tell us back
if the message cannot be delivered to some recipients.
This allows to send large files, such as APKs,
when using providers that don't have such strict limits.
Although it does a little for security, it will help to protect from unwanted server-side
modifications and bugs. And now we have a time to test "multipart/signed" messages compatibility
with other MUAs.
- If bcc_self is set, gossip headers must be added despite of the number of group members.
- If another device observes Secure-Join, instead of looking for Secure-Join-Fingerprint in
"vg-member-added"/"vc-contact-confirm" messages it must use keys from Autocrypt-Gossip headers as
described in the Countermitm doc
(https://countermitm.readthedocs.io/en/latest/new.html#joining-a-verified-group-secure-join).
This allows to distinguish exceptions,
such as database errors, from invalid user input.
For example, if the From: field of the message
does not look like an email address, the mail
should be ignored. But if there is a database
failure while writing a new contact for the address,
this error should be bubbled up.
