Command in custom header

Applications

Evolution 3.46.4 Arch Linux
I want to use a command in a custom header.
Is this possible?
I need the date command to schedule my mails.
like date --rfc-email -d '1 day 10:00'
My email provider can handle this with a schedule IMAP folder.

Hi,
the custom headers plugin allows only static strings, not commands.

If you want this to schedule the send time by saving the message to a
certain folder on the server, instead of sending it, then you can use
an Outgoing Filter (in Edit->Message Filters, change the type at the
top), where you can ā€œPipe To Programā€ and that program can add the
header at (the top of) the message. You can even configure your IMAP
account to use ā€˜sendmailā€™ instead of SMTP and have the filter store the
message into the right folder. Unless itā€™s the SMTP server which
understands that date header; Iā€™m not sure from your text how it is.

You can also create a composer plugin, which will do all of it for you.
An example of it is here:

Thank you,
I will take a closer look on filters.
