Net_NNTP is a PHP/PEAR library for communication with NNTP servers. Net_NNTP handles connection and protocol-level commands (RFC977), including many non-standard commands (RFC2980), via a user-friendly API which hides the actual NNTP commands/syntax. Some knowledge about NNTP and general knowledge about email and MIME is required, since parsing of content and headers is left up to the user. Net_NNTP allows advanced users direct usage of NNTP commands via the separate protocol implementation. Net_NNTP includes a fully-functional NNTP to HTML gateway demo application.
Swift is a library for sending email messages from PHP Web sites and applications. It does not rely on PHP's native mail() function (which is known for using high server resources when sending multiple email messages). Instead, it communicates directly with an SMTP server or an MTA binary to send mail quickly and efficiently. It features custom headers, multiple encoding options, TLS support, embedded images, building and sending multipart messages, fast Cc and Bcc handling, batching messages with or without multiple "To"s, support for multiple attachments, setting message priorities, requesting read receipts, pluggable SMTP Authentication (LOGIN, PLAIN, MD5-CRAM, POP Before SMTP), anti-flooding support (reconnect every X email messages ), secure Socket Layer connections (SSL), and loadable plugin support with event handling features.
