The mailing list for listmasters using Sympa

[<address@concealed>]

We want to implement sympa at our institute, but we have a slight problem: The
users in our LDAP directory have mail aliases so they can use:

address@concealed
or
address@concealed

and they use both types to send their mail.

We need to have the way to define for messages to be accepted from both
adresses but distributed to only one of them (so that users don't get double
posts etc.). I can't see any option where I can define aliases for subscribers
addresses. Is that possible? If not, I think it should be because I believe
that people really need it. :)

The only thing that I can think of is to write a custom perl module to query
the LDAP directory for aliases and compare them to subscribed adresses and 
than
add it to the scenari. But I don't think that I can make the unbsubscribe to
work that way.
