I am having issue that Yahoo emails are not reaching recipients. I am getting an error message but after 24hrs not even straight after. It's only come to my attention because in follow up calls, they are telling me that the emails never arrived..
Please advise me how to sort it out as is very important I can reach those yahoo recipients.
Your message couldn't be delivered. Despite repeated attempts to contact the recipient's email system it didn't respond.
Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their email system isn't accepting connection requests from your email system. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.

My issue is with emails sent to yahoo addresses through the web based outlook and live.co.uk domain. Assuming this is the blacklisted ip issue in this instance?
Many thanks

The same goes with SPF regardless of where your mail host is (cloud or on premise). Besides that, getting your ISP to change the static IP reverse lookup (PTR) is not that easy. It's easier to create an SPF record.
Yes it was simpler back then, an MX record is all you need and all SMTP servers were open relays but very few abused it. Look on the bright side, SMTP servers are a lot more secure today compared to 25+ years ago.
