p3pmail provides a tool that removes dangerous HTML tags from email.

p3pmail will remove dangerous HTML tags from email messages to make them safer for viewing. It does this by skipping the header of the email message before parsing it for dangerous HTML tags. It will only parse HTML email.

You have to set up a port redirection with iptables so that all connections from e.g. inside your office to any POP3/POP3S/SMTP server outside in the world will not leave your router, but come to a local port, on which P3Scan listens.

P3Scan receives from the Linux kernel the original destination (the email server outside in the world) and will connect to them.

All data we receive from the client will be sent to the server, and vice versa. With a little enhancement: we parse the necessary parts of the protocol and when an email is sent from the server, we store it into a file, invoke our scanning, and send it along if it is good, or in the event of POP3/POP3S we replace it with a virus notification and optionally delete the infected message. For infected SMTP messages, we reject the message.

It should be possible to use all scanners using the scannertype=basic.
Also, P3Scan provides scannertype=avpd for high-speed scanning using Kaspersky Anti-Virus for Linux, every C programmer can easily adept other scan-daemons (trophie, sophie, antivir, ...).

Neither the client nor the server has to be configured, none of them will take notice that theres a mail scanner (except the client when he gets a virus notification or if he looks into the header, and the server gets our ip as source).

Pop3eye is a pop3 email notifier, previewer and spam deleter. It can be run as a dockapp or as a regular or undecorated window that pops up when checking email.
Pop3eye can notify you of email from specific people, with certain subjects, or with information in any other header line by using regular expressions as filters.
It can display up to 20 partial lines of the email body in a tooltip window. Any number of accounts can be monitored and each can have its own color and font scheme.
Pop3eye 0.6 has undergone heavy reworking of regular expression pattern matching. You can setup expressions to match on any header line and then show or hide the email, or delete emails from the server without downloading them.
A log of deleted emails can be kept. You can set "test-delete" until satisfied with its operation.
A portion of the "From:" and "Subject:" lines are displayed as they are retrieved. Afterward, only those marked "show" will be seen.
Mouse actions affect only the account under the mouse. Right clicking on one account retrieves only for that account. Right clicking during retrieval will abort.
If your pop3 server supports UIDL, already downloaded headers and body text will not be downloaded again unless some emails have been deleted. You can force it to download with "shift-right-click".
Enhancements:
- A memory leak has been fixed.
- Retrieval to a local file and deleting email messages from the server can be done to all accounts simultaneously with Shift-Right-Click.

EMailRobot is a simple object-oriented framework for developing email auto-responders.
It performs actions based on parameters extracted from received email bodies and generates answer emails.
Enhancements:
- Minor fixes were made and documentation and installation notes were added.

Perl Pop3 is a POP3 server fully implemented in Perl.
The advantages over other POP3 servers are that it is not a memory hog, and can be used to connect to databases for authentication.
Also, its code is easy to extend for any other uses, like POP-before-SMTP and extended logging.
Main features:
- Does not read the mailbox into memory, it reads what it needs as it processes the mailbox, so its memory requirements are low.
- Most email delivery is just printing out to the client; this is done in a fast and efficient way.
- It uses the systems users in the default unix way, but it can be changed to read users off a database (using DBI/DBD). It is prepared to use the database right away and can be extended or configured to use existing systems.
- It can be use to solve the smtp authentication via popauth or relay-domains (with sendmail) so users can be permitted to send smtp mail after pop3 authentication. This has been an effective solution for roaming users.
- Logging can be extended beyond the use of text files to any other method available in Perl, including database systems.
- Also, security is not an issue, as input is strictly controlled.
Using an easily modifiable daemon as part of a e-mail solution can be of great advantage over other existing systems in other languages. Further development will also try to incorporate more easily configurable extensions and plugins, so rapid deployment and extensibility is achieved.
Installation:
For installation instructions and configuration please see the INSTALL file. For more detailed information, consult the DOC file.

The Email Server is designed to provide services offered by its commercial email products, such as IMAP/POP services, Web-Based Email Interface and Administration, Mail Filtering, Spam Blocking and Directory-Based Authentication and Addressbooks.
RH Email Server is fine for businesses and organizations of all sizes. Multiple commercial and educational installations are already using this project. The largest current user load that has been reported is 7,000 + users.
Interoperability between RHSD projects such as the RHSD Email Server and the RHSD Domain Controller will allow for use of Single-Sign On. RHSD also utilizes IETF Standardized projects and therefore will be compatible with any Directory system compatible with LDAP v.3.
Main features:
- Web-Based Email Client for Users
- LDAP Directory / Authentication
- Mail Filtering
- Addressbooks
- Web-Based Administration Tools
- Role-Based Tool Delegation
- Spam Blocking

WizMail is a Webmail system that strives to keep synchronized with the email on a POP3 server so that it can be accessed from the Web when an email client cant be used, and then downloaded when possible.

It is also able to filter incoming email into different folders, offers different configurable identities and signatures per user, and supports drag and drop.

WizMail project supports downloading and relaying of email using any SMTP/POP3 client: using WizMailTunnel, your email server can be accessed through HTTP/HTTPS proxies.
