Adam, What 'email' topology/setup do you use? The error that you are recieving looks like it's trying to push two or more statement to the SQL server at the same time (common SQL issue). Have you double checked your DSN via: http://support.ipswitch.com/kb/IM-20001219-DM02.htm ? If you are not hosting massive amounts of email clients, you and your email server, will rest a lot easier using the native imail 'registry' database.

I am running most recent version of Imail server. I looked in the sys logs today and saw a bunch of weird entries that i have never seen before, these entries just keep showing up throughout the log and seem to be present around the same time as SMTP is using alot of cpu time. The log entries look like this: 12:05 15:50 ODBC(155044339) (Table: (null)) Initialize:SQLDriverConnect (Check userid and password on server.) 12:05 16:26 ODBC(162605339) (Table: tblUser) IsValidTable : (Error: # HY000 : [Microsoft][ODBC SQL Server Driver]Connection is busy with results for another hstmt) 12:05 16:26 ODBC(162605339) (Table: tblUser) CreateTable : (Error: # HY000 : [Microsoft][ODBC SQL Server Driver]Connection is busy with results for another hstmt) These lines do not make any sense to me. It looks as if someone or something is trying to create table's within my user database or something like that. Could this be someone attacking our server? ___________________________________________________________________ Virus Scanned and Filtered by http://www.FamHost.com E-Mail System.
