Go to Services > OrMail and click '+'.
Enter the HS Address and Port you got from the recipient, the External
Address you want her to see as To: address and a Local Address, which
you intend to use in your mail client as To: address.
Click the Accept button to close the window.
Make sure the activation checkmark at Services > OrMail is set!
Then go to the User tab, select your user entry and click '=' to open
it.
At the OrMail Recipients list set a checkmark for the Local Address item
of your recipient to assign it to your user.
Click the Accept button to close the window.
Restart servers.
Now each message with the recipient's Local Address term as its To:
address sent by your user takes the OrMail route. The delivery will
only succeed when at that moment the recipient's Hidden Service is
online.

The major advantage of remailer networks is unpredictable latency at each server[end quoted plain text]
of the delivery chain, which renders correlation attacks useless, an important >contribution to its extremely reliable resistance against all kinds of attacks.
But that latency may be intolerable with time-critical missions, where also the
feedback of a successful transaction is mandatory, which remailers can't provide
as well.
That's where direct e-mail communication between sender and recipient through >the Tor network may be a viable solution.
It gives you hidden end-to-end encrypted data transfers in realtime e.g. between
OmniMix installations, which are connected by a circuit of up to 9 anonymizing >Tor nodes, without the need of an additional external mail server.
Like anonymous remailing through the Mixmaster and Yamn network OrMail >integrates seamlessly into your mail management infrastructure. Use your standard

Then go to the TorPlus > HSvcs tab to set up such a Hidden Service for incoming
OrMail by clicking the '+' button to add a new item. >Tutor_TorPlus_OrMail_HS_Edit
Create a new folder, where Tor deploys Hidden Service data like the .onion >address it computes at a later restart. Then enter a random external port number
at 'Port Ext'. Better don't use a standard port, which is easier to detect by an
adversary. Set 'Int Address' to '127.0.0.1' for the local computer as the device
where the OrMail SMTP server resides, and enter its port number into the 'Port >Int' field.
With a restart of the OmniMix servers and Tor the system is ready to receive >OrMail messages. That's when the Hidden Service's .onion address is created and
gets visible at the AddrExt column of the Hidden Service table. A click on the >'*' button of the Hidden Services list now copies the complete OrMail address >looking like >'ormail2q4v4tsqtqludlts4cbmk5y5u2d74x6aus7tol642uxi2qh3yd.onion:54321' into the

Now go to the 'User' Accounts tab, select your own user item (e.g. the >'OmniMix'/'omnimix' entry) and, for testing purposes, add a '^.*$' item, a >regular expression term for all possible addresses, to the 'OrMail Addresses' >list.

That's it at the receiving end. Now to the easier task at the sender. >Presuming that Tor is already running you first have to go to the Services > >OrMail tab, click the '+' button to add an item and define the OrMail recipient

Then at 'Local Address' enter a (short) unique describing term that you use as >the recipient's address in your mail client, and at 'External Address' the true

After closing that window check the activation box above the OrMail Recipients >list.

Finally, back at the 'User' tab, activate that OrMail address at the 'OrMail >Recipients' list for your account as shown in the picture above to make it >available.
