[dba-Tech] BLAT

Hi All:

I have set up a client, who has some legacy software (command based), with
the email client BLAT exe file. When testing it appears to be working
correctly but when running this on the client's site there appears to be
some instability. Sometime the message goes through and sometime not. 

I have not been able to create an error checking routine that catches all
the errors. I am also wondering if the BLAT dll might be a better way to go?
Is the better option than BLAT? I am not sure whether the IPS host is
translating some of the emails as spam?

Any suggestions or alternatives would be greatly appreciated.

Jim
