`mailer_command` was removed, and a new setting `send_mail` was added.
Its possible values are a string, consisting of a shell command to
execute, or settings to configure an smtp server connection. The
configuration I used for testing this is:
[composing]
send_mail = { hostname = "smtp.mail.tld", port = 587, auth = { type = "auto", username = "yoshi", password = { type = "command_eval", value = "gpg2 --no-tty -q -d ~/.passwords/msmtp/yoshi.gpg" } }, security = { type = "STARTTLS" } }
For local smtp server:
[composing]
send_mail = { hostname = "localhost", port = 25, auth = { type = "none" }, security = { type = "none" } }
conf_override! wraps struct definitions and defines a secondary Override
struct that wraps each field in an Option. The macro mailbox_settings!
is used to select settings from an account & mailbox index. If a user defines an overriding setting, the macro returns the override instead of the immediately next in the hierarchy setting.
The selection is done for a specific field as follows:
if per-folder override is defined, return per-folder override
else if per-account override is defined, return per-account override
else return global setting field value.
Merge ui crate with root crate.
In preparation for uploading `meli` as a separate crate on crates.io.
Workspace crates will need to be published as well and having a separate
`ui` crate and binary perhaps doesn't make sense anymore.
