Can I use port 587 instead 25?
Originally, the Simple Mail Transfer Protocol (SMTP) used port 25. Today, SMTP should instead use port 587 — this is the port for encrypted email transmissions using SMTP Secure (SMTPS). Port 465 is also used sometimes for SMTPS. However, this is an outdated implementation and port 587 should be used if possible.
What is the default port for Apache Windows?
Listen: to bind Apache to specific IP addresses and/or ports. HTTP server, by default, runs on port 80 for production. For testing, you could choose a port number between 1024 to 65535, which is not used by an existing application (you can run command " netstat " to check the existing connections).
