Email Validation

Hey,

I am a Software developer from Europe.

I have a client that would like to verify an email-List via the application atompark.com. The application says, he has to connect to port 25 for this.

Unfortunately this is not my field of expertise.

Could anybody help me out?

Thank you in advance.

You need SMTP for validation and its not the easy thing cause servers get blacklisted in the Email validation your customers need below things.
If email list is more than 100k SMTP should be linked with atleast 30 IPs under rotation.

Good Luck.

Thank you for the reply.

He probably assumed that the whole thing would be a little easier
