Copy mail file from maildir over ssh

The maildir has a specific format of the files laying underneath, e.g. *1549464014.9224_427.hostname:2,RS*. In Debian environment copying this file over SSH without renaming is impossible or I don't know how. The question is how? **NOTE:** no renaming should be involved! The example output: [user@hostname ~]$ scp '1549464014.9224_427.hostname:2,RS' remote.server.com:/dest/dir/ 1549464014.9224_427.hostname:22: [Errno -2] Name or service not known The solution with quotation like in https://unix.stackexchange.com/questions/438791/scp-error-while-attempting-to-copy-files is not useful.
