If you turn off DKIM signing, does it get faster?

How big is the opendkim process?

I still have trouble believing a disk-only or even memory-only configuration is introducing delays of the size you're talking about.

Ok sorry to take so long to get back, was testing some things. It would seem that the tool that my guy was using to send his emails from would wait for a response from the server before moving on to the next email for verification on if it was successfully sent or not. Since it has to obviously add the dkim signature before its sent it was slowing it down, so while it would still be nice to know of any specifics on increasing this speed its not imperative at the moment because there are work arounds. Basically just means while the implementation of dkim is what made it go slower dkim is not the problem, I told him he probably should programming some multi threading into his app with progress bars for better results. Anyway thanks for providing the troubleshooting steps they helped me figure out the specifics.

Sorry what do you mean by the MSA entries, I am not entirely up to speed with sendmail so if you could tell me what I am looking for in the logs I will see if I can get it for you.

Post an extract of the mail log from the time the (mail) client submitted the message to the time the message was accepted by sendmail. You mentioned that it takes around five seconds for that. What we are looking for is whether it actually took five seconds and what sendmail was doing.
