Roy RainfordUsing Mail v11.5 on my iMac and OS 10.13.6 High Sierra, emails are not coming through the POP Account. They do appear on my iPad and iPhone. They also show in Mailbox Manager. I can't see anything wrong with the settings in Mail Prefs or in System Prefs. This problem only occurs for my TalkTalk "toucansurf.com" address. Emails via my iCloud address come through. What settings should I check?
