Whether you're handing off to a sendmail process, or making a port 25 connection to localhost (or your smart host), your web app will typically wait until either sendmail returns or the receiving MTA has successfully sent a "250 2.0.0" response back. There could be any number of things slowing down the mail server. Some examples: 1. 'net-based spam/virus checks. 2. Slow DNS. 3. Slow 'net connectivity. 4. Lack of separation into MSA/MTA. 5. Load on the system itself. 6. Some bad configuration option. You really need to look at each individual case and figure out where the bottleneck is.
