Those following me on the Fediverse has recently become familiar
with an old-school program called Mail Avenger. 


```
mkdir ~/.avenger
openssl rand -base64 8 | shasum | head -c16 > ~/.avenger/.macpass
echo "" >> ~/.avenger/.macpass
```

```
brew install berkeley-db4
curl -O http://www.mailavenger.org/dist/avenger-0.8.5.tar.gz
echo "b0fc3e2e03ed010e95e561367fce7b087968df7ea6056251eba95cad14d26d37 avenger-0.8.5.tar.gz" | \
      shasum -a 256 --check
tar xvzf avenger-0.8.5.tar.gz
cd avenger-0.8.5
./configure --with-db=/usr/local/Cellar/berkeley-db@4/4.8.30
cd util
make macutil && install macutil ~/.local/bin/
```

```
macutil --expire=+2M --from "Tommy S" --fromexp "address expires" --sender "t+return+*@252.no"
```
