My mail.log is overflowing with random spammers attempting to send spam through my server.
Is this typical or have I misconfigured something?
Is there a way to ban an IP after several attempts of relaying or is there a way not to log these attempts? (latter might be a bad idea)
I have a directory with .patch files, generated using diff.
I would like to apply all those patches using patch -p1 to another directory.
But patch takes only one file, unless I cat.
What would the command be to apply multiple files using xargs or a similar tool.
