Thanks for your information. I found your stated article in
It is extracted from Sendmail Conference program in O'Reilly Open Source
Convention held in August. However, I read the presentation found in
It described how LDAP map lookup implementation are improved. Here is one:
"Keep connection open for entire transaction
- Previously opened connection for each query"
It seems the connection is kept open for each SMTP transcation, and not
amongst all different SMTP connections. If that is the case, it wouldn't be
a great improvement. Am I understand wrong?
Sorry for a bit off-topic.
