POPauthd is a Perl-based daemon that uses POP to authorize connecting hosts for SMTP relaying. It is particularly useful to authenticate roaming users with IP addresses that change often. The daemon runs in the background, watching the syslog for successful POP logins. When it sees one it enters the IP in sendmail's access database, giving the host authorization to relay through the server. The entries can be expired after a prescribed, configurable period of time with a companion script run via crontab.
kmMail is a PHP-based mail program, based on the mail functionality of Keftamail and is being developed by current Kefta employees. It is meant to be a framework for putting a web-based mail program on your site, but is still robust enough to drop into your current site with little to no modification. The goals of kmMail are MIME compliance, speed, low overhead, and an enjoyable user interface.
JFetch is an application to download your email through protocols like POP3 and IMAP. The decision of whether to download a mail or not is made through a sequence of filters. By implementing certain interfaces, a user can very easily add his/her own filter to the current set of provided filters. Examples of filters are spam control, size restrictions, etc. JFetch downloads the email if it matches the criteria and then can deliver it using one of its delivery options.
Designed as a Perl framework to support many different types of POP and email servers, Mobile POP Relay is useful for mobile users. Once a user successfully authenticates against a POP server, relaying is allowed through the server for a specified time period. It supports Ipop3d, Qpopper, and Vpopd with Sendmail or Exim.
Replex is an administrative tool for managing email on any Unix-like OS. It can handle multiple domains, users, mailing lists, etc. without requiring creation of Unix user accounts for mailboxes or authentication. Replex is written in PHP4 and stores all information in a MySQL database. Replex relies on Postfix for SMTP and Cyrus for IMAP and POP3 accounts.
Websieve Scripting Tool is a Perl CGI script that allows users to create complex Sieve syntax filtering rules, including a vacation response message, using a simple form on a Cyrus IMAP mail server. It also allows the setting of mailbox ACLs and password changes (LDAP and Qualcomm poppassd).
POP 3 client is a PHP class that allows you to access mail boxes using the POP3 protocol. It provides a stream wrapper class for retrieving messages like files using the PHP fopen function, establishes secure connections using TLS, accesses servers using normal and APOP login methods, supports authentication mechanisms such as PLAIN, LOGIN, CRAM-MD5, NTLM (Windows or Linux/Unix via Samba) via the PHP SASL library, and supports listing of message sizes, retrieval of a message at once, separating the headers from the body, retrieving a message in small chunks to not exceed the available memory, and deleting messages.
chk4mail lists the number of read and unread messages in all the folders in your mail directory and inbox. This is especially useful to people who automatically filter their mail to several folders. It supports standard mbox format, MMDF, MH, Maildir, and remote mail folders using IMAP.
