an SMTP implementation

[ommy]

Hello people
I am stuck here with a little problem. As i am intrested in doing a little socket programming. I was looking for SMTP implementation. i got it downloaded from the net. Now I want to know about it that how it works. I have certain confusions about the code, that I want to clear. I am uploading the soucrce (smtp.c file) and I have commented every line with my confusion. I hope some one expert in socket programming will help me out with this.Yesi know it would take a little time but would be a great contribution towards my learning
Thank you all...for reading

Sorry I don't mean to be rude but googling ip socket programming (http://www.google.com/search?q=ip+socket+programming) may give you better info rather than waiting for one here (the first link is good). But before start programming sockets, you need to understand the basic TCP/IP protocols (like SMTP) work. I see you are also confused on some basic C functions work like snprintf, so you may need to refresh your C knowledge.

Like you, I tend to learn programming by examples. But the funny thing is sometimes I don't have enough time (deadlines, yes...) to fully understand how things work. As long as I'm sure (by a few trials and errors) when I do this it'll do that, that's enough for now. Just modify some parameters and it works like I want it to. Understanding will come eventually. ;)

My two cents.

Peace always,
