SMTP server need multiple user logon due IONOS security change (emails must logon using email domain), I have several domains.
IONOS on 29/01/2024 require emails sent via SMTP to be from the domain of the email.
eg 111.com, 222.com & 333.com
I have three domains with ionos so I need to be able to logon using three different users.
eg fred@111.com, bert@222.com & jim@333.com
all to SMTP.ionos.co.uk
BUT Thunderbird appears to only allow ONE USER for each SMTP server.
Attempting to change user changes ALL instances of logon to smtp.ionos.com.
