Het programma Courier is een opensource 'mail transfer agent', ook wel mailserver genoemd, voor Unix- en Linux-systemen. Het beschikt onder andere over esmtp, imap, pop3 en de mogelijkheid om via webmail e-mail te lezen en te versturen. Voor meer informatie over Courier en zijn mogelijkheden verwijzen we jullie door naar deze pagina. De ontwikkelaars hebben versie 0.60.0 de deur uitgedaan met de volgende veranderingen sinds de vorige vermelding in de Meuktracker:
Version 0.60.0:Version 0.59.0:
- Adjust default SSL/TLS settings. Fix a bug in TLS session caching.
- Clean up configure scripts and makefiles.
- Several portability fixes.
- Fix parsing of email addresses with backslashes.
- Add POP3 login timeout.
- Update internal documentation.
- Implement the ability to authenticate using SSL certificates. courier-authlib 0.61, or higher, required.
- Set a null return address for mail forwarded by sqwebmail-generated mail filters.
- Remove SSL CA bundle from the package, use system-installed SSL CAs.
- Optimizations to IMAP keywords. A trade-off with concurrency: faster speed in exchange for a race condition if two concurrent sessions attempt to update keywords on the same message -- the last one wins.
- Several portability fixes.
- Strip any trailing periods in sender and recipient addresses' domain names.
- imap: Optionally disable maildir ownership sanity check, controlled by a new setting: IMAP_MAILBOX_SANITY_CHECK
- webmail: Autorenaming of the Sent folder can be turned off in preferences.
- Fix %{ir} macro expansion in SPF records.
- Update default SSL/TLS settings to be more liberal by default. Affects new installs only, will not touch existing configuration on upgrade.
