Problem with Courier authentication services

[vafe]

Today in one of my servers after a stop for maintenance I find these with the following error in the log of courier

Code:

Oct 15 10:42:28 multi syslog: exec: No such file or directory
Oct 15 10:42:28 multi syslog: exec: No such file or directory
Oct 15 10:43:20 multi pop3d: Connection, ip=[::ffff:201.219.81.60]
