connecting to mobileme mail via telnet

[oliverw92]

Hi there,

I have started to look into making a simple email client that might be web based, but i am not sure of that yet. i have been experimenting with some telnet sockets from terminal and some php raw sockets. however i have come across a problem when connecting to mobileme mail. i can log on successfully and enter all the data but once i have finished the data header i get this error: <-- 550 5.7.0 From address is not one of your addresses. i have no idea what it means. i tried using a packet sniffer to see what Mail sends when it sends mail and i then compared this to what my simple php script sends and i cannot see any differences. i was wondering if anyone had any insight on this matter. here are the logs from the packet sniffer and my php script

I posted this thread in mac programming but thought it might be better off here. ill see though

packet sniffer on Mail:

<-- 550 5.7.0 From address is not one of your addresses.

i can log on successfully and enter all the data but once i have finished the data header i get this error: <-- 550 5.7.0 From address is not one of your addresses.

Generally, this means that MM believes that your "from" address (oliverw92@mac.com) "doesn't belong to you". It's typically an anti-spam/anti-forgery "feature" enforced by the mail sender.

Now, "oliverw92@mac.com" may belong to you, but the system doesn't think so. Are you using a different login/account? You probably have to use the same address that belongs to the account. (Or, maybe, MM insists on having @me.com addressses only?) Try sniffing the output of Mail.app or Thunderbird, to see what they use.

the first one i posted is the output from the Mail.app being inspected from Packet Peeper. the second is what my php script outputs. im loggin on with exactly the same base64 of my user and pass (i copied and pasted what mail.app sent to make sure).

thanks for replying btw

OK, sorry, I missed that.

IIRC, you might be running into another anti-spam countermeasure: some spam-generating programs would send EHLO followed immediately by the next command (AUTH, in your case) without waiting for the EHLO reply. I think some servers automatically assume that, if you don't wait for the EHLO reply before sending the next command (AUTH), you're a spammer, and reject your mail. Try processing the EHLO replies before sending AUTH -- the last line is "250", immediately followed by a space, and the last EHLO-param ("SIZE 0", in your example).

However, in some cases, I think the last line (the only line, possibly) might be indicated by "250" followed by the last EHLO-param (no space, and no "-"). I'm not sure. Perhaps someone who knows more about SMTP can comment.
