Just came across the following logged message which failed to be parsed by our log parser:
postfix/anvil[29988]: statistics: max message rate 4/60s for ([2001:1470:ff80::25]:10088:2001:1470:ff80:88::80:c) at Dec 8 19:26:44
Btw, 10088 is a port number, not part of an IP address. Perhaps an IP address should be enclosed in brackets to avoid ambiguity. No big deal, just commenting... Mark
