Mailcrypt makes strong cryptography a fully integrated part of your normal mail and news handling environment. Read more mailtrace reads a mail header on stdin and dumps a trace of smtp hosts in a human readable manner on stdout Mikrop a small, easy to install program for e-mail servers to scan incoming e-mails.

OdeiaVir designed to integrate virus scanning into an e-mail server. It curently only supports qmail as an MTA and McAfee VirusScan for Unix as an AV scanner pgp4pine pgp4pine is a PGP shell for Pine. pgp4pine has two modes: Incoming and outgoing. In "incoming" mode, it mostly just invokes PGP to decrypt or verify the message. In "outgoing" mode, the recipients are checked first and based on the result, an appropriate list of choices is presented. pgpenvelope a Pine filter written in Perl that allows one to use encrypt/sign/decrypt/verify one's email messages with GPG or PGP5 Pine Privacy Guard a small perl script to interface Pine and GnuPG for the secure exchange of email Qmail-Scanner an addon that enables a Qmail Email server to scan all gatewayed Email for certain characteristics. It is typically used for its anti-virus protection functions, in which case it is used in conjunction with commercial virus scanners QuarantineAttachment a seventeen line procmail script fragment can be used to quarantine most malicious Microsoft Outlook attachments rbl-milter a simple sendmail milter which adds an X-RBL-Warning header to any emails that are received that come from an open relay as determined by your choice of RBL checking service receivedIP for auditing the IP addresses in e-mail "Received: " headers, and contains parsers and high speed database query programs to validate IP addresses in e-mail RenAttach an e-mail filter/processor that runs from a user's .forward file. It is designed to protect end users (particularly those using Windows) from malicious e-mail attachments containing viruses or trojans sig2dot can be used to generate a graph of all of the signature relationships in a GPG/PGP keyring, like those resulting from keysigning parties, or the Debian Keyring smtpmap smtpmap determines the version and name of the smtp server running on the target system with a fingerprint technology. Sophos PureMessage (commercial) a complete email filtering system for spam protection, virus protection, and corporate policy enforcement SwenDeleter SwenDeleter tries to identify email messages infected with the Swen. A worm in POP3 mailboxes and delete them on the server.

This is intended to be a tool for users to identify phishing, fradulent emails asking for the user's sensitive data, and zombie-spread viruses claiming to be from someone they are not. Topal Topal is yet another program that links GnuPG and Pine/Alpine. It offers facilities to encrypt, decrypt, sign, and verify messages. Multiple PGP blocks included in the text of a message are processed. Decryption and verification output can be cached to reduce the number of times the passphrase is entered. RFC2015/3156 multipart messages can be sent and received with help from some scripts, procmail, and a patch to Pine/Alpine. There is a high level of configurability.
