(From Newsletter #49, Feb 27, 2023)

Most of the more popular E-mail services are changing their requirements for using through a 3rd-party application like Campground Master.  If you haven't already made the required changes, you may suddenly find that you can't send E-mail from Campground Master when they "transition" your account to the new requirements.  Assuming your are using a version of Campground Master recent enough to support the needed changes, you can make the changes now to avoid interruption.

GMail -- they seem to be making it a requirement to use the new OAUTH2 authentication, so we are recommending that everyone use this since it's easier than trying to keep up with their other security requirements.  Version 11.0 or later is required for this.  See our documentation for details:

Yahoo -- They have recently added new settings that are required for using 3rd-party apps, which must be set through your Yahoo account.  See our documentation for details:

Office365 -- They are making it difficult to use 3rd-party applications, but it MIGHT be still possible with some changes in your Office365 settings.  See our documentation for details:

MS Exchange -- They are making it difficult to use 3rd-party applications and will be completely disabling basic SMTP, if they have not already done so.

However, we recently heard that if you didn't make these changes before December 31s, 2022, then it's already too late.  It will require changes to the Campground Master software in order to use MS Exchange, similar to the changes we made for GMail.  Look for this in a future version of Campground Master.

GoDaddy -- If you use GoDaddy for your web service and E-mail account, they have switched to using Office365 -- see above.

Other E-mail servers -- Most servers are requiring you to use a secure port, usually either 465 (SSL) or 587 (TLS).  If you still use port 25, then it may still appear to work but your E-mails may not reach the customer because it will be considered non-secure by the receiving server.  So be sure to check with your provider and use the most current settings information.  See our documentation for details:

Also note that Campground Master version 9.2 or later is needed for "TLS level 1.2" required by most E-mail servers now.
