release-1.5
b2be4de

This release improves the handling of the IMAP & IMAPS probes, to ensure that once a login-test has been made a logout operation also occurs. This was a grievous omission which caused false-failures when probing remote dovecot servers.

Assuming a test every minute then after ten minutes the probe would start failing with this error message:

  • Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10)

Adding the logout operation, and ensuring that the connection is closed properly removes this false-positive.
