When I try to do any "email-related" task in Storefront like "Email Receipt" or when any automatic email is supposed to be sent, the email fails and I get an error message like below.
I have gone through all of the trouble-shooting steps here https://www.revindex.com/...efront/rvdwktid/257:
I have verified that the smtp settings are correct (test email works fine) and I tried setting the smtp user name, the host email, the Storefront email recipient/sender all to the same address (hostmaster@rapidbi.tech) and I still get the same error - the same problem happens with multiple accounts at different levels (i.e. the same error happens when signed on as 'host' or as 'sampleuser', for example).
I have not modified the email template (any template, in fact) in any way.
Please let me know what I need to do to address this issue.
