SquirrelMail is een in php geschreven programma om webbased e-mail mogelijk te maken. Het wordt door verschillende isp's gebruikt om webmailfunctionaliteit aan te bieden. Het programma heeft ondersteuning voor de imap- en smtp-protocollen en alle schermen worden in html 4.0 opgebouwd, zonder dat hiervoor javascript nodig is. De ontwikkelaars hebben na de twee release candidates die in augustus vorige jaar werden vrijgegeven eindelijk SquirrelMail 1.4.20 de deur uitgedaan met de volgende aankondiging:
SquirrelMail 1.4.20 Released
The SquirrelMail Team is pleased to announce the release of SquirrelMail version 1.4.20. This release makes final the changes implemented in our last two release candidates and adds several smaller fixes and feature improvements.
Of those new fixes and improvements not included in our last release candidate, the most notable fix is that for the formerly broken search page, but we've also fixed sorting in the Sent folder, handling of complex mailto: addresses, display of multibyte subjects, quoting of encoded headers, automatic installation address detection (especially useful for lighttpd environments), a privacy issue related to DNS prefetching of email content, and added unread links in the message view and a Gmail IMAP configuration option.
For more complete details, see the ReleaseNotes and ChangeLog files included in this release (in the doc/ directory).
Due to the security fixes included in our last two release candidate packages, we advise all users of SquirrelMail versions 1.4.19 and below to upgrade.
