[PHP] [QUESTION] MAIL: Send a NOOP instead of DATA
I wrote a class to send mail by remote mail server.
But it was failed. So I captured the network packets by tcpdump,
and found that there is a strange packet NOOP was sent.
But in the source code I mean to send command DATA.
I don't know why a NOOP packet was sent instead.
Here is my php source code and the attachment is tcpdump file.

Manuel Lemos said the following on 2008-1-16 11:55: Maybe you are accessing a SMTP server with a grey listing or anti-spam/anti-virus frontend that sits on the front of the actual SMTP server and only passes information to the backend server when it is ready. It is possible that your message is malformed and the frontend server is expecting something that you are not sending correctly. Meanwhile the frontend server sends NOOP commands to the backend server to keep the connection opened. But it's strange that php should send a DATA command out, but tcpdump didn't capture this packet. :( You may want to try this SMTP class that is known to work correctly according to the mail standards. See if you can send the message properly. If so, the theory above is likely to be the case. http://www.phpclasses.org/smtpclass If you need authentication, you also need this: http://www.phpclasses.org/sasl Thanks Manuel, I will try this. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It seems to me that is something is altering the data you are sending for some reason. I suggest that you ask your system administrator. For debugging my code, I use tcpdump to capture packets and compare the difference between outlook's packets and php's packets. By the way, i only have one NIC. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks much, y'all. Forgive to my typo on the original email.

[PHP] Add buttons on the fly
I would like to add two buttons on a page form infomation confirmation, however, the html code in php nest can not be known by browser if I put form xxx input xx /form into there. Besically, there is a mail form to enter iterm infomaiton, if it exist before, prompt its iterm id., if it is new, query a next available inerm id for it, then, show a page to ask such as, do you accept this id?, two buttons below this question, yes and no. Is there any fountion in php which can make it? Thanks.
