net-mail flameeyes@gentoo.org Enable support for network protocols (POP, IMAP and SMTP). If you only need to send mail with the local Transport Agent, disabling this will get you support for only /usr/sbin/sendmail call. If network is enabled, this adds support for S/MIME and SSL/TLS-powered protocols through dev-libs/openssl. If network is enabled, this adds support for GSSAPI login on IMAP through virtual/kerberos.
