grknight@gentoo.org Brian Evans 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/krb5.
