+       Bugfix (introduced: Postfix 3.0): LMTP connections over
+       UNIX-domain sockets were cached but not reused, due to a
+       cache lookup key mismatch. Therefore, idle cached connections
+       could exhaust LMTP server resources, resulting in two-second
+       pauses between email deliveries. This problem was investigated
+       by Juliana Rodrigueiro. File: smtp/smtp_connect.c.
