The latest version of Redcarpet still have this problem (we upgraded Redcarpet to 3.4.0 in r16583).

Redmine is not affected by the respective issue because we have no_intra_emphasis: true and the emails with _ are recognised correctly. Please see the below screenshot.

The issue with <a_bc@def.com> looks to be from the same Redcarpet gem, the text is filtered out because it is recognised wrongly as HTML tag.

Rails console:

With :filter_html => true:

irb(main):012:0> Redcarpet::Markdown.new(Redmine::WikiFormatting::Markdown::HTML.new(:filter_html => true, :hard_wrap => true), autolink: true, no_intra_emphasis: true).render("<a_bc@def.com>")
=> "" 

With :filter_html => false:

irb(main):013:0> Redcarpet::Markdown.new(Redmine::WikiFormatting::Markdown::HTML.new(:filter_html => false, :hard_wrap => true), autolink: true, no_intra_emphasis: true).render("<a_bc@def.com>")
=> "<p><a_bc@def.com></p>\n" 

Using CommonMark Markdown instead of Redcarpet-based Markdown can avoid the issue.

Please switch to CommonMark Markdown. Redcarpet-based Markdown was marked as "deprecated" (#36807) in Redmine 5.1.0 and will be removed in the future version.
