Turns out for Protonmail there is no limit on how much email you can receive. The 150/day limit is for sending emails, not receiving. I think it's enough for general usage. I will gradually transit some communications to PM.

Only thing is the 500MB storage limit. But for now I got the habit of delete every email I read except important ones. Emails with large attachments can also be downloaded and deleted. So it should work for at least a few years of time. Maybe after a few years they will increase the storage!

it's a waste of time to focus o what you don't have, or could have done better. what is in your control is making the most of what you have today, and taking the steps to create the future that you want and deserve. if you are able to face the future without fear -- if you can face it with the strength and conviction that you can handle whatever comes your way --- your future will indeed be bright.

       The syntax for requesting multiple files from a remote host is done by specifying additional remote-host args in the
       same style as the first, or with the hostname omitted.  For instance, all these work:

           rsync -av host:file1 :file2 host:file{3,4} /dest/
           rsync -av host::modname/file{1,2} host::modname/file3 /dest/
           rsync -av host::modname/file1 ::modname/file{3,4}

       Older versions of rsync required using quoted spaces in the SRC, like these examples:

           rsync -av host:'dir1/file1 dir2/file2' /dest
