Problems with connecting to the Virgin email servers
I have an iMac and use Apple Mail to access 3 Virginmedia email accounts and I Blueyoner email account. for approx 1 month I have been experiencing problems connecting with the email servers. Sometimes the they connect sometimes they don't connect, sometimes they connect and disconnect. This is happening many times in an hour. When they don't connect it reports problem with password etc. then 5mins later they connect. My Mac is up to date, I also use Bit Defender. Has anyone any idea what I can do?
