FossaMailهو بريد إلكتروني مفتوح المصدر، قائم على Mozilla Thunderbird، عميل أخبار ودردشة لنظام Windowsولينوكس، مقدمًا من مطوري Pale Moon (ومن ثم ليس له صلة بشركة Mozilla Corporation). إنه إصدار بديل من عميل البريد والأخبار Mozilla Thunderbird، ومعتمد على نواة متصفح Pale Moon.

ميزات FossaMail:

• This is a security and maintenance update, updating the platform code to Pale Moon 27.2.1.
• Please see Pale Moon's release notes for details on the updates involved.
• Important note: If you have previously changed the configuration to enable deprecated/vulnerable cipher suites to connect to old mail servers (you really should upgrade those where possible; e-mail by design is private so secure encryption is very important!) then you will most likely need an additional step:
• In Options, go to Advanced, open the Config Editor, find security.tls.insecure_fallback_hosts and add your insecure host(s) to it (comma-separated). This is needed for RC4 and 3DES.
