    not really "Cprogramming" question about email

    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.

    Does your implemetation 100% fits the SMTP RFC? Maybe there is something wrong with your terminating character sequence (As I remember it must be sometinh like <CR><LF>.<CR><LF>)

    Maybe use ethereal to trace and analyse the protocol messages being sent and received by a standard application and your application?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
