According to the November automated survey of about 700,000 mail servers, Exim holds a share of 58.73% (down from 60.90% a year ago), while Postfix is used on 34.86% (up from 32.49%) of mail servers, Sendmail \u2014 3.46% (down from 3.51%), MailEnable \u2014 1.84% (down from 1.91%), MDaemon \u2014 0.40% (down from 0.42%), and Microsoft Exchange \u2014 0.19% (down from 0.20%).       <\/p>\n<p>  Key Changes:  <\/p>\n<ul>\n<li class=\"l\"> A utility exim_msgdate has been implemented to convert message identifiers (message-id) into a readable format.\n<li class=\"l\"> The testing mechanism for string disclosure, invoked when starting Exim with the `-be` option, has been updated to allow the setting of variables.\n<li class=\"l\"> A client-side generated event has been added and <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3848\">server<\/a> for authentication failure via SMTP AUTH.\n<li class=\"l\"> A new variable $sender_helo_verified has been added, which contains the result of applying the ACL `verify = helo`.\n<li class=\"l\"> Support for predefined macros for disclosing elements, operators, conditions, and variables has been added.\n<li class=\"l\"> Early disclosure of the SMTP option `max_rcpt` has been ensured (prior to usage).\n<li class=\"l\"> In the tls_eccurve option for OpenSSL, acceptance of a list of group names has been provided.\n<li class=\"l\"> Queue handlers can now be launched from a single background process.\n<li class=\"l\"> An operator for splitting long header lines has been added.\n<li class=\"l\"> A command-line option has been added to output only message IDs in the queue.\n<li class=\"l\"> The ${readsocket} disclosure operator now allows setting SNI for TLS.\n<li class=\"l\"> In the ACL modifier remove_header, specification of regular expressions is now permitted.\n<li class=\"l\"> A variable $recipients_list has been added, containing a properly escaped list of recipients.\n<li class=\"l\"> For log_selector, a parameter has been implemented to reflect incoming connection identifiers.\n<li class=\"l\"> Five vulnerabilities discovered in late September have been resolved, three of which (CVE-2023-42115, CVE-2023-42116, CVE-2023-42117) allow remote code execution without authentication on <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-newyork\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"
