+Subject: [PATCH] Fix pattern for sendmail queue ID to parse ones with PID
+ having 7 digits.
+
+Sendmail 8.15 uses the following format for queue id:
+- 6 letters or digits dependent on date and time,
+- 2 letters or digits dependent on random sequence ID,
+- PID of sendmail process formatted by snprintf using "%06d" format.
+
+Format "%06d" means that resulting string has *minimal* length of 6 characters,
+padded with leading zeroes if necessary.
+But if PID is greater than 999999, the resulting string can be longer,
+up to 7 characters if kernel.pid_max sysctl parameter is big enough.
+By default it's 32768, but can be up to 4194304 on 64-bit systems.
+
+This change fixes logwatch to parse sendmail log lines produced by
+sendmail processes that have 7-digit PID.
