Hi, I have problem with saslauthd keeps killing its child one at a time after dovecot sends back an OK IMAP response message. My Dovecot is running on an email proxy that communicates to my internal email server. As far as I can tell, dovecot has responded positively on the login attemp. I also checked the raw IP data and it shows the IMAP OK response packet. Here's the dovecot log: Dec 21 17:13:53 lawang dovecot: auth(default): client in: AUTH^I4^IPLAIN^Iservice=IMAP^Ilip=10.11.3.1^Irip=10.11.3.2^Iresp=<hidden> Dec 21 17:13:53 lawang dovecot:
