The mailing list for listmasters using Sympa

["Allen, Pat" <address@concealed>]

First off, I apologize if this has been asked and answered before. I've found 
discussions relating to it in the archives but I couldn't find any solutions.

I've installed a second virtual host on my Sympa 5.3.4 installation using the 
instructions that have been provided. Everything appears to be working fine 
so far except for the sendmail aliases. Sendmail ignores anything after "@" 
on the left hand side of an alias definition. This has the unfortunate effect 
of causing duplicate alias definitions which overwrite each other.

My current aliases look like:
sympa: "| /home/sympa/bin/queue address@concealed"
listmaster: "| /home/sympa/bin/queue address@concealed"
bounce+*: "| /home/sympa/bin/bouncequeue address@concealed"
abuse-feedback-report: "| /home/sympa/bin/bouncequeue 
address@concealed"
sympa-request: postmaster
sympa-owner: postmaster

address@concealed: "| /home/sympa/bin/queue 
address@concealed"
address@concealed: "| /home/sympa/bin/queue 
address@concealed"
address@concealed: "| /home/sympa/bin/bouncequeue 
address@concealed"
address@concealed: "| /home/sympa/bin/bouncequeue 
address@concealed"
address@concealed: postmaster
address@concealed: postmaster

I know that there are installations out there that have virtual hosts and 
sendmail working together. How do you do it?

Thanks!
Pat Allen
