## 项目历史与用法

mailcheck is a small command-line utility for checking multiple mailboxes for new mail. The official homepage and upstream manpage document support for mbox, Maildir, POP3, and IMAP.

### 项目历史

The upstream manpage says mailcheck was written for Debian GNU/Linux by Jefferson E. Noxon, with copyright years spanning 1996, 1997, 1998, and 2001. POP3 and IMAP support is credited to Rob Funk.

The official 1.91.2 SourceForge release contains a compact C program, manpage, sample `mailcheckrc`, and Makefile. Its install target places the command under `/usr/bin` and the default config under `/etc`.

### 采用历史

mailcheck's adoption is traditional distribution packaging rather than a large upstream community. The input package-manager facts list Homebrew, Debian, Ubuntu, and Nix, and the official homepage links Debian package information.

### 使用方式

The manpage recommends invoking `mailcheck` from `/etc/profile` or a user-specific login script, with `-l` login mode respecting `~/.hushlogin`. It reads `~/.mailcheckrc` first and falls back to `/etc/mailcheckrc` when no user file exists.

Configuration is line-oriented: local mailbox paths or Maildir directories, plus `pop3:` and `imap:` URLs for remote mailboxes. Passwords are not stored in `mailcheckrc`; for POP3 and IMAP, the manpage says credentials come from `~/.netrc`.

### 为什么软件包爱好者会关心

mailcheck is package-nerd archaeology in useful form: a tiny C utility from the login-shell mail-notification era, still packaged because it has few moving parts and interoperates with old mailbox formats and `.netrc` credentials.

### 时间线

- 1996: Earliest upstream copyright year in the manpage.
- 1998: Additional copyright year and mailbox/network support lineage appear in the manpage.
- 2001: Later copyright notice appears in the manpage.
- 2007: SourceForge published the mailcheck 1.91.2 release tarball.

### Related projects

- The manpage points users to biff, mail, fetchmail, netrc, and ftp as related Unix mail and credential tools.
