# s-nail local mailbox setup

## Goal
s-nail → custom sendmail stub → /var/mail/root

## 1. Check s-nail
```sh
s-nail -V

```

## 2. Create sendmail stub

```sh
cat >/usr/sbin/sendmail <<'EOF'
#!/bin/sh
MAILBOX="/var/mail/root"
FROM="root@andromeda"
{
    printf 'From %s %s\n' "$FROM" "$(LC_ALL=C date '+%a %b %d %H:%M:%S %Y')"
    cat
    printf '\n'
} >> "$MAILBOX"
EOF

chmod 755 /usr/sbin/sendmail

```

## 3. Configure s-nail

```sh
echo "set mta=/usr/sbin/sendmail" > /root/.mailrc

```

## 4. Init Mailbox

```sh
rm -f /var/mail/root
touch /var/mail/root
chmod 600 /var/mail/root

```

## 5. Test & Verify

```sh
echo "Test mail" | s-nail -s "Test" root
s-nail -H

```

## 6. Mbox Ops

```sh
s-nail
# d 1       -> delete
# save 1 X  -> export
# q         -> quit

```

```
