Curl SMTP on Linux Invalid From address

Runbox Chat
#1

I got Thunderbird setup and can use that or the web client for the regular tasks, but need an automated way to send just a few emails. I’m trying to use ‘curl’ (8.7.1) which has worked well for this sort of thing with other email providers. It says I have an invalid From address, but I am using my default identity (not an alias). I’m getting the following error:

 curl -v --url 'smtps://mail.runbox.com:465' --ssl-reqd \                                         
 --mail-from 'boxturtlebakery@runbox.com'  \
 --mail-rcpt <mytarget>@gmail.com \
 --upload-file body.txt \
 --user boxturtlebakery
...
> MAIL FROM:<boxturtlebakery@runbox.com> SIZE=107
...
* upload completely sent off: 112 bytes
< 550 Invalid From address. Please see https://help.runbox.com/identities/

I can use something else to if someone has another open-source piece of software that works well with the Runbox services.

Thanks for any help.
