Thanks a lot Wietse... i understood that 'address_verify_map = memcache' is used to make persistant the verify database, but according to your words i was wrrong: it will make memcahe the database itself.. Am i right? Thanks! Pete.

You could try https://www.postfix.org/memcache_table.5.html - Give it enough memory. - Be sure to block remote access. - Specify "address_verify_cache_cleanup_interval=0" on all hosts except one (to avoid spikes in memcache load). Wietse
