They work successfully in Debian v11.6/64 bit Linux environment.
Now I have connected an IP video camera that can send email over SSL to port

I just do what you recommend.
How do I need to do this reconfiguration?
Please tell me about this in more detail.
And another question: do these commands hav
I think I've followed all your instructions, and now I've got another mistake:

Dear Viktor,
I'm is an old grandfather, and I'm already not thinking straight in Linux and

But I very need to get this stubborn and also old Videocam to work :-)
