continuation of long aliases

[John Hascall]

In sendmail, when an alias grew
​too ​
long, you did:


alias:
​ ​
recip1, recip2, recip3, ... recipN, continue-1

continue-1:
​ ​
recip
​​
N+1,
​ ​
recipN+2, ... etc


This seems not to work in postfix.
How do I deal with really long aliases (~50,000 addresses)?

Thanks,
John
