The mailing list for listmasters using Sympa

address@concealed"> Hello everyone,

I have a sympa server that receives emails to lists on the domain listas.xpto.pt and listas.another.pt, listas.another.pt it's an alias to listas.xpto.pt, so every list can receive email to both domains, eg, address@concealed is the same as address@concealed


So far every email the list sends to a subscriber goes as address@concealed as this is the main robot domain.

I have to change the main domain so that a mail sent by sympa goes as address@concealed, but I'd still want to receive email to the list when using the alias listas.xpto.pt.

If I change the main robot domain to listas.another.pt, will sympa behave and keep receiving email to both domain, but send from new main robot domain?

Yes, provided you handled redirections correctly.
The trick with such a setting is to make sure that each mail reaches the main robot.
Example: You have one robot with domain a.tld. You want it to accept mails addressed to domain b.tld. Tou must then rewrite addresses in "b.tld' to "a.tld". this way, the addresse "address@concealed" will finally be handled as "address@concealed" and consequently match the Sympa aliases.

Using sendmail , I have this configuration:

I have this line in sendmail.mc:
FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable.db')dnl

And this one in /etc/mail/virtusertable:
@a.tld       a.tld-%1%3
@b.tld       a.tld-%1%3

The aliases Sympa generates have the following form:

a.tld-mylist: "| /usr/local/sympa/bin/queue address@concealed"
a.tld-mylist-request: "| /usr/local/sympa/bin/queue address@concealed"
a.tld-mylist-editor: "| /usr/local/sympa/bin/queue address@concealed"
a.tld-mylist-unsubscribe: "| /usr/local/sympa/bin/queue address@concealed"
a.tld-mylist-owner: "| /usr/local/sympa/bin/bouncequeue address@concealed"

So now, if you want to switch, i.e. make b.tld the actual Sympa domain, and a.tld the redirection, all you have to do is:

1- change the Sympa domain in sympa.conf withour restarting

2- change virtusertble to rewrite a.tld.to b.tld:

@a.tld       b.tld-%1%3
@b.tld       b.tld-%1%3

3- change the aliases to replace all occurrences of a.tld to b.tld:

b.tld-mylist: "| /usr/local/sympa/bin/queue address@concealed"
b.tld-mylist-request: "| /usr/local/sympa/bin/queue address@concealed"
b.tld-mylist-editor: "| /usr/local/sympa/bin/queue address@concealed"
b.tld-mylist-unsubscribe: "| /usr/local/sympa/bin/queue address@concealed"
b.tld-mylist-owner: "| /usr/local/sympa/bin/bouncequeue address@concealed"

4 Restart Sympa and sendmail

As both domains are already routed to your Sympa server, this operation should be very quick if you script it.

Regards,

David
