Hello boys and girls,
I'm developing a simple SMTP client in C, and it works well: the only problem is that the emails I send take a long long time before be delivered (about 20 minutes) while using other "professional" apps with the same message this time is about 1 minute. I made the tests at the same time of the day, and I continously foud that difference in the delivery time: does anyone have any help/link/idea ? Do I forget any "x" field in the description of the message perhaps? I only use smtp protocol!!
Thank you for your help, and sorry for posting perhaps in the wrong post.
