Redhat ES4 qmail-1.03 qmail-ldap-1.03-20041201.patch Courier-imap-4.02-1.4ES openldap-2.2.13-2 squirrelmail-1.4.3a-9.EL4
Users are able to login to squirrelmail send and receive but once in a while squirrelmail complains.. when sending a new message Service not available, closing channel Server replied: 421 unable to read controls (#4.3.0) Logout.. Log back in and send works qmailctl stat reports that all is well. and services are up ps axf .... reports no problems. Have no idea where it might be coming from. qmail logs look normal. Nothing popping up. Does any have any idea where I can start looking.. Thanks
