hi,
here am I too... sorry for the delay but I did not get any notification of your answers. But I am happy to see that someone of the mods is interested to solve the issue

And yes, I dont get notified about new private messages too.
here my screenshot. As you can see I also have enabled the appropriated options in the setting.
Interessting is that when I login I get a pop that I have new private message, do I what to view it -> YES, but i dont get forward to the new message. I have attached a screenshot of thre private messaging settings too.
My emails from comodo forum should be delivered to my private email address, from where ALL the emails are forwarded to my 2. private email address (without being deleted from the 1. email address, so i always have to copies of each email). I searched in both email addresses for emails from comodo and could not find anything, so no comodo emails in the inbox, spambox, trash or elsewhere. This was just to clarify that the issue is not caused by my email adresses.
