"unreasonable virtual_alias_maps result" ERROR !

[jabc]

Hi everybody

I have installed Release 8.8.7.GA.1964 on UBUNTU 14.64 x64 FOSS edition. I create one distributiion list with 520 accounts to send internal news but when I try to send mail I recieve the follow error in logfile:

Jun 5 09:40:51 dns2 postfix/cleanup[11381]: warning: 7D5BC12BCB3D: unreasonable virtual_alias_maps result "jsaldana@acest... -- message not accepted, try again later
Jun 6 09:40:35 dns2 postfix/cleanup[1337]: warning: C0D9212BE9FF: unreasonable virtual_alias_maps result "jsaldana@acest... -- message not accepted, try again later

By default virtual_alias_expansion_limit = 10000

I tried with postconf -e virtual_alias_expansion_limit=20000 restart postfix and nothing, same problem but virtual_alias_expansion_limit=10000 (did'nt change)

I tried too with zmlocalconfig -e postfix_virtual_alias_expansion_limit=20000 and same problem.

Somebody have some idea or know how fix it ?

Thanks
