history

Project history and usage

LibEtPan is a portable C mail framework for IMAP, SMTP, POP, NNTP, local mailbox formats, MIME, and RFC 822 style message handling.

Project history

The project presents itself as a portable and efficient framework for mail access in C. Its older NEWS file records releases in the 0.28 to 0.45 range during 2003-2006, with early work on IMAP fixes, maildir support, MIME parsing, Berkeley DB-backed caches, SSL/TLS, SASL, PGP/S/MIME, Windows support, and cross-compilation.

Adoption history

The etpan.org project page identifies LibEtPan as the low-level API used by MailCore and MailCore 2, then lists downstream use in Mac and iOS mail applications as well as Claws Mail and other clients. That placement gave it a long life as a reusable mail-protocol layer below application-specific user interfaces.

How it is used

LibEtPan is used either as a C library linked through pkg-config or through platform project files for macOS, iOS, and Windows. The upstream site includes examples for composing MIME/RFC 2822 messages, downloading IMAP and POP messages, and sending SMTP mail.

Why package nerds care

For package maintainers, LibEtPan is a dense networking library with many optional protocol surfaces: SSL/TLS, SASL, local mailbox formats, MIME generation, and multiple server quirks. Its ChangeLog shows the maintenance style of a real mail library, with repeated compatibility work for specific IMAP servers and encodings.

Timeline

  • 2003: The NEWS file records libEtPan 0.28 on April 1, 2003 and 0.29 on October 6, 2003.
  • 2005: The NEWS file records versions 0.36 through 0.41, including Windows support, SASL, S/MIME, and PGP work.
  • 2011: The ChangeLog records libetpan 1.1 on July 12, 2011 with IMAP NAMESPACE, SMTP SIZE, and progress-report API improvements.
  • 2013: The 1.2 tag was dated June 4, 2013 on GitHub.
  • 2014: The 1.5 and 1.6 tags were dated May 5, 2014 and October 31, 2014.
  • 2019: The 1.9.4 tag was dated November 1, 2019.
  • 2026: The 1.10 tag was dated May 22, 2026, and the repository page listed a 1.10.1 release dated June 14, 2026.

Related projects

  • The project page explicitly connects LibEtPan to MailCore and MailCore 2. Its feature list also places it near mail clients and libraries that need IMAP, SMTP, POP, NNTP, mbox, MH, Maildir, MIME, and RFC 822 handling.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for libetpan. Nucleus package metadata is still published here so future coverage has a stable package URL.

Install behavior

  • No Homebrew post-install hook is recorded in formula metadata.
  • Homebrew bottle metadata is available for 6 platform targets.
  • Installs with 1 runtime dependencies.
  • Build metadata lists 4 build dependencies.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
