Done that. Sending from the VM, now I get
msmtp: the server does not support DSN
msmtp: could not send mail (account default from /home/richard/.msmtprc)
I tried with no auth and with auth off and get the identical result,
Reading the manual again, I see that DSN is Delivery Status
Notification. Although it is the default, I have tried specifying
dsn_notify off, but still get the same error.
Info on the ISP's smarthost from their site:
and we will relay messages that fulfill the following criteria:
* The envelope MAIL FROM: address must be routable (i.e. exist and
have a valid MX record)
* The envelope RCPT TO: address must also be routable.
* To connect to the relay your host IP address must be in the Bytemark
* The message must be 20MB or smaller.
* Your machine is not sending more than 240 messages every 6 hours.
Only the first two could be a problem AFAICS. How do I get to see the
envelope msmtp is trying to send?
I also ran msmtp -S which gives:

[22.214.171.124]), port 25:
