After loading the latest update, I can't send emails. Spamhaus is blocking them. this is an example of the error message... this is a business I have emailed before and they are in my address book, it is doing the same with other addresses

Sending of the message failed. An error occurred while sending mail. The mail server responded: Service unavailable; Client host [68.105.172.193] blocked using an77miiefpoizgkgitohtqs2qa.zen.dq.spamhaus.net; https://www.spamhaus.org/query/ip/68.105.172.193. Please check the message recipient "service@renaissance-printing.com" and try again.

I viewed the URL you posted and it states that your problem is that you are not using SMTP authentication on your outbound mail. I suggest you review and correct that and see if the problem disappears.

It says the SMTP is authenticated by password transmitted insecurely

I suggest setting connection security so password is secure and try again. Either ssl/tls or starttls should work unless it's a site that uses oauth2.
