it works fine after de-installing G-Data.
Ah ok so was G-Data that was the problrm.
There has also been some other customers using that security program who had issues as well receiving and sending mail, and had to end up uninstalling or disabling G-Data to get eM Client to work.
Just something weird with the way G-Data works that blocks eM Client. Hopefully in the future G-Data can update their program to work with it.
Wonder which internet security I can use.
I cannot reccomend any third party security / firewall or antivirus programs you can use, but other users on this forum might reccomend some. Whatever you use generally you will need to configure it to allow eM Client to work.
I personally just run Win 10 & 11 & Mac OS Ventura with “the default built-in Firewalls and Antivirus / Malware programs” and never needed to buy or use any optional ones. Works fine for me.
