If in doubt read documentation.

$ man 5 memcache_table
MEMCACHE_TABLE(5) File Formats Manual MEMCACHE_TABLE(5)
...
NOTE 1: When using a memcache table as postscreen(8) or ver-
ify(8) cache without persistent backup, specify a zero
*_cache_cleanup_interval value with all Postfix instances that
use the memcache, and specify the largest postscreen(8) *_ttl
value or verify(8) *_expire_time value as the memcache table's
ttl value.
NOTE 2: According to memcache protocol documentation, a value
greater than 30 days (2592000 seconds) specifies absolute UNIX
time. Smaller values are relative to the time of the update.
