Re: Finding subject in POP3 connection

Using those commands you can get the message headers (and first 10 lines of the message) by doing something like this: USER username PASS password LIST TOP 1 10 TOP 2 10 ... TOP 100 10 QUIT Here's a pseudo-code example: open connection to pop3-server.mydomain.com port 110; send "USER username"; send "PASS password"; send "LIST"; read list of messages; for each message_id returned by LIST { send "TOP $message_id 10"; read message header; print message title to user; } send "QUIT"; close connection; Here's a screen-dump of a telnet session doing the above, and it can be easily duplicated in php with the fsockopen(), fputs(), fgets() and fclose() functions (you should also look at the set_socket_blocking() function). ---[ SCREENDUMP START - names changed to protect the guilty ;-) ]--- jesper@juhl:~$ telnet mymailserver.mydomain.com 110 Trying 192.168.1.123...

QUIT +OK Closing connection. Goodbye. Connection closed by foreign host. ---[ SCREENDUMP END ]--- If you need more details, then just ask.
