In their own words
MailWasher
MailWasher previews email on the mail server so users can remove unwanted messages before downloading them to a computer. Its filtering tools include Friends List, Blacklist, RBLs, custom and learning filters, a profanity list, and spam ratings. The free edition works with one email account and has no support; Pro supports unlimited accounts and POP3 and IMAP. Firetrust lists Gmail, Outlook.com, Yahoo, AOL, and Hotmail, along with programs such as Outlook, eM Client, and Thunderbird. The maker says email content stays on the PC and only the license key is sent to its servers. It also says MailWasher uses OAuth for services such as Gmail and Outlook.com, or app passwords, rather than asking users to enter their actual email passwords in the app. Mobile apps are available for iPhone, iPad, and Android. Pro has a 30-day trial with full functionality. Listed purchase options include $49.95 a year for one year, $77.21 a year for two years, $99.90 a year for three years, or 149.95 USD once for a lifetime license; annual plans thereafter cost $34.95 a year.
Rspamd
Rspamd is an email security engine for filtering phishing, business email compromise, malicious attachments, and spam. It scores messages using reputation, sender authentication, content analysis, and machine learning. Authentication checks cover SPF, DKIM, DMARC, and ARC; malware scanning can use ClamAV or commercial antivirus engines. Administrators can define custom rules through the Lua API and configurable maps and selectors. Rspamd works with mail transfer agents including Postfix, Exim, and Sendmail, and its ClickHouse and Elasticsearch integrations provide visibility into attack patterns and detection rates. It is designed for gateway deployment and can run on-premises, keeping message data in the operator's environment without a mandatory vendor cloud. The detection engine is open source under Apache 2.0 and is available for Linux, macOS, and self-hosted use. Rspamd says its event-driven C core scans hundreds of messages per second per core and can scale from a single server to billions of messages a day. The open-source engine is listed at free. Scale costs £100 a month, with 5K mailboxes; hosted and enterprise plans have custom pricing. Premium plans offer support from core engineers, with enterprise SLA options.
