I have a telefonica,net and an iCloud.com email on my imac. When I try to send an email in any of these I receive a Too many authentications message and it will not be sent. However, I continue to receive emails?
I have tried many sites and their recommendations but all have failed to resolve the issue. I have changed the default port to 26 or 587, for example. Any assistance would be appreciated
