Aliasing: Why and Whom


Why:

The main reasons to alias an address to another one might be:

Quota problem

The targeted @ can only accept a limited amount of messages per day or per hour, it is a commercial POP or forwarder
The owner of the targeted address supplies alternate addresses, just like as many parallel pipes, multiplying the total usable quota
The people deciding to alias to an alternate address:
----will not be disturbed by people using another pipe
----will not disturb people using anothe pipe
----users a,b,c,d alias to alternate address 1, with [total a,b,c,d] < quota
----users e,f,g,h alias to alternate address 2, with [total e,f,g,h] < quota
----commoners still use the non-aliased address, nominal address
e.g. say:
----BigFoot has a quota of 3.000 messages/day/address
----*all* remailers alias the nominal address to alternates
>>>the nominal address remains *completely* free for commoners (i.e. end-users)
----because only 5-10% of traffic comes from end-users while 90-95% comes from other remailers
>>>such a remailer would sustain 30.000-60.000 messages/day.
(BigFoot's quota is doomed to decrease to 25 messages/day, killing that solution and Frog)

Permanent bad connexion

The targeted @ has a bad connexion or is offline most of the time / too often: that might create a tremendous CPU burden on a remailer trying to send to that address, with retries and connections lockouts.
The owner of the targeted address supplies an alternate address (a commercial POP) which is easily fed by those not willing to take that burden.
He will then download from time to time from that POP.
Example: Cmeclax

Temporary bad connexion

The targeted @ has a temporary bad connexion (packet loss...): that might create a tremendous CPU burden on a remailer trying to send to that address, with retries and connections lockouts.
The owner of the targeted address did not spontaneously supply an alternate address (a commercial POP).
The sender creates a temporary address at a forwarder's (sneakemail) and aliases the targeted address to the forwarding address.
Mail will (hopefully) land in the destination mailbox, but the burden of retries will be taken by the forwarder...
Example: Lsd

Redundancy

The targeted @ spontaneously offers an alternate route in case anything unpleasant happens.
It can be:
--an alternate dynamic DNS route (in case the dynamic DNS supplier would be down
----Example: yi.org/hn.org/no-ip?dynip
--a commercial POP3 if the remailer is down
Example: Frog2

Mail2news

Mail2news basically provide the same service.
In case one is down for a long duration, it might be aliased by another one, to avoid posts emerging way behind the argument is closed.
