That is a good question, they are actually not the same but the same. Let me explain. There are two mail stacks in perl `libmail` and `libemail`. libmail* libmail-authenticationresults-perl - object oriented Authentication-Results headers libmail-dkim-perl - module to cryptographically identify the sender of email libmail-sendmail-perl - simple way to send email from a perl script libmail-spf-perl - Perl implementation of Sender Policy Framework and Sender ID libmailtools-perl - modules to manipulate email in perl programs libmail-box-imap4-perl - perl module for handling of IMAP4 folders as client libmail-box-perl - message-folder management module libmail-box-pop3-perl - POP3 handler for Mail::Box libmail-bulkmail-perl - Platform independent mailing list module libmail-checkuser-perl - Perl module for checking email addresses for validity libmail-chimp3-perl - interface to mailchimp.com's RESTful Web API v3 libmail-deliverystatus-bounceparser-perl - module for analyzing bounce messages libmail-dmarc-perl - Perl implementation of DMARC libmail-field-received-perl - mostly RFC822-compliant parser of Received headers libmail-gnupg-perl - Perl module for processing email with GPG libmail-imapclient-perl - Perl library for manipulating IMAP mail stores libmail-imaptalk-perl - IMAP client interface with lots of features libmail-listdetector-perl - module for detecting mailing list messages libmail-mbox-messageparser-perl - Perl module for processing mbox folders libmail-mboxparser-perl - module providing read-only access to UNIX mailboxes libmail-message-perl - generic class representing mail messages (perl library) libmail-milter-perl - Perl extension modules for mail filtering via milter libmail-pop3client-perl - POP3 client module for perl libmail-rbl-perl - Perl extension to access RBL-style host verification services libmail-rfc822-address-perl - Perl extension for validating email addresses libmail-sendeasy-perl - Perl module to send plain/html e-mails through SMTP servers libmail-spf-xs-perl - library for validating mail senders with SPF - Perl bindings libmail-srs-perl - interface to Sender Rewriting Scheme libmail-thread-perl - library for threading email by In-Reply-To and References libmail-transport-perl - perl library for sending email libmail-verify-perl - Utility to verify an email address libmail-verp-perl - Variable Envelope Return Paths (VERP) address encoder/decoder libemail* libemail-address-xs-perl - Perl library for RFC 5322 address/group parsing and formatting libemail-date-format-perl - Module to generate RFC-2822-valid date strings libemail-abstract-perl - unified interface to mail representations libemail-address-list-perl - RFC close address list parsing libemail-address-perl - Perl module for RFC 2822 address parsing and creation libemail-date-perl - Perl module for correct formatting of dates in emails libemail-filter-perl - library for creating easy email filters libemail-find-perl - module to find RFC 822 email addresses in plain text libemail-folder-perl - Perl module to read mail from a folder libemail-foldertype-perl - module to determine the type of a mail folder libemail-localdelivery-perl - module to deliver a piece of email - simply libemail-messageid-perl - Perl library for unique mail Message-ID generation libemail-mime-attachment-stripper-perl - module to strip attachments from an email libemail-mime-contenttype-perl - Perl module to parse a MIME Content-Type header libemail-mime-createhtml-perl - multipart HTML email builder libemail-mime-encodings-perl - unified interface to MIME encoding and decoding libemail-mime-kit-perl - module to build complete email messages from templates libemail-mime-perl - module for simple MIME message parsing libemail-outlook-message-perl - module for reading Outlook .msg files libemail-received-perl - Perl module to parse an email Received: header libemail-reply-perl - module to reply to an email message libemail-sender-perl - Perl module for sending email libemail-simple-perl - module to parse RFC2822 headers and message format libemail-stuffer-perl - casual approach to creating and sending Email:: emails libemail-thread-perl - library providing threading for Email::Simple objects libemail-valid-loose-perl - Email::Valid which allows dot immediately before at mark libemail-valid-perl - Perl module for checking the validity of Internet email addresses The second was created as reaction to the former getting more and more complex and bug prone. See at the description for example: """ Description-en: module to parse RFC2822 headers and message format Email::Simple is the first deliverable of the Perl Email Project, a reaction against the complexity and increasing bugginess of the Mail::* modules. In contrast, Email::* modules are meant to be simple to use and to maintain, pared to the bone, fast, minimal in their external dependencies, and correct """ Now you could say "everybody could say that" but look at the dependency tree. Even "libmail" nowadays starts to use "libemail" in some places. For example Package: libmail-dmarc-perl Recommends: libjson-perl, libmail-dkim-perl, libnet-http-perl, libnet-imap-simple-perl, libnet-server-perl, libnet-smtps-perl Filename: pool/universe/libm/libmail-dmarc-perl/libmail-dmarc-perl_1.20230215-1_all.deb root@m:~/libemail-mime-perl-1.953# apt-cache show libmail-dmarc-perl | grep libemail Depends: perl:any, libconfig-tiny-perl, libio-socket-ssl-perl, libfile-sharedir-perl, libnet-dns-perl, libnet-idn-encode-perl, libnet-ip-perl, libnet-ssleay-perl, libemail-mime-perl, libtest-file-sharedir-perl, libemail-sender-perl, libdbix-simple-perl, libdbd-sqlite3-perl, libtest-output-perl, libregexp-common-perl, libsocket6-perl, liburi-perl, libxml-libxml-perl, publicsuffix So the summary is: - yes they provide different functionality - but at different complexity levels and coexisting for a long time due to that - We'd not want to rip apart the whole lib[e]mail stacks to just settle on one, the perl community probably knows better than us (and then the maintenance update would come on top) Therefore we'd request to consider those not duplicates, despite having the same top level functions. P.S. Happy to be told I'm wrong by actual perl experts :-)
