Hello Williamfromroswell,
I understand that you are experiencing an issue with your Apple Mail rules not automatically running when new emails are downloaded from Mindspring. This problem has recurred for you, and it was previously resolved when you updated macOS, but the recent update to Ventura 13.4 did not fix it.
You mentioned that you found a workaround with Apple Support, which involves duplicating an existing rule, applying it, and then having all the rules run as expected to scan your inbox. Afterward, you simply delete the duplicate rule. However, given the high volume of emails you receive daily (300+), this workaround becomes inconvenient. The issue started around 6/7or8/2023. Thank you for providing this information.
In cases like this, it is recommended to try a few troubleshooting steps to resolve the problem:
1. Rebuild mailbox: In Apple Mail, you can try rebuilding the affected mailbox by selecting the mailbox in question, going to the "Mailbox" menu, and choosing "Rebuild." This action can resolve issues related to mailbox corruption.
2. Reset Apple Mail preferences:
Quit Apple Mail, then navigate to
~/Library/Containers/com.apple.mail/Data/Library/Preferences
and move the "com.apple.mail.plist" file to the desktop. Restart Apple Mail, and it will create a new preferences file. Note: That this will reset your Apple Mail preferences, so you may need to reconfigure settings afterward.
If the issue persists after trying these steps, it may be worth reaching out to Apple Support for further assistance. They have access to advanced troubleshooting tools and can provide specific guidance based on your system configuration.
Please keep in mind that the information provided here is based on general troubleshooting practices, and it's advisable to consult official Apple support resources or contact Apple Support directly for the most accurate and up-to-date assistance.
Best regards,
Lugab
