emails sent from upstage.live (minor issues)

[helenvarley]

i sent a test email today from the email interface in upstage.live, & there are 2 minor issues:

• i got a bounce on it from an undeliverable email address that looks like something quang did for testing. i guess this address should be taken out of the code?
• i put the UpStage logo in the signature, but it's not displaying for me in the email (neither in thunderbird or in webmail, so i think it's not just me).

in thunderbird:

in webmail (tuta):

i've just tried deleting and reinserting the UpStage logo in the email signature - there was an incorrect filepath; but this has not fixed the problem.
& still got the bounce on the old quang email.
