PHP script to process incoming emails

Need to have a PHP program under Linux to use IMAP function [login to view URL] to: 1. read an email account 1.1 if there is no new email, exit here 2. loop through each new email, if there is an attachment (an attachment may have multiple files): 2.1 if the attachment is >15 MB: 2.1.1 email the sender back that attachment size is too large 2.1.2 goto 2.3 2.2 check if the email is from a recognized email address (use SQL to query a MySQL database) 2.2.0 record the time of attachment downloaded 2.2.1 if the email is from a recognized email address: 2.2.1.1 download the attachments and save the attachments to a directory (tmp_dir) 2.2.2 if the email is not from a recognized email address: 2.2.2.1 if the total attachment size is >2 MB: 2.2.2.1.1 do not download the attachment 2.2.2.1.2 email the sender back that attachment size is too large 2.2.2.1.3 goto 2.3 2.2.2.2 if the attachment is <2 MB: 2.2.2.1.1 download the attachment and save the attachment to a directory (tmp_dir) 2.2.3 email the sender back that: 2.2.3.1 the attachment is successfully received 2.2.3.2 the size and filename of each attached file 2.2.3.3 time of attachment downloaded 2.2.4 save the details of the email into a database (use SQL to write to a MySQL database), one record for one file in the attachment. E.g. if there are 5 files in the attachment, there will be 5 new records 2.2.4.1 sender email address 2.2.4.2 each filename of the attachment 2.2.4.3 size of each filename 2.2.4.4 time of attachment downloaded 2.3. delete the email from IMAP 3. exit Your PHP program will be run under CRON job every minute. In order to filter bot reply, please submit your bid by stating what 2.2.4.1 above is. Please let me know if you need further information. Below is the skeleton of the code that I have created so far and you are free to change it. <?php // set user to check $strUser = "user@ [login to view URL]"; $strPassword = "123123pwd"; $mail_server = "[login to view URL]" // open $hMail = imap_open ("{$mail_server:993/imap/ssl}INBOX", "$strUser", "$strPassword"); // get headers $aHeaders = imap_headers( $hMail ); // get message count $objMail = imap_mailboxmsginfo( $hMail ); // process messages for( $idxMsg = 1; $idxMsg <= $objMail->Nmsgs; $idxMsg++ ) { // get header info $objHeader = imap_headerinfo( $hMail, $idxMsg ); // get from object array $aFrom = $objHeader->from; // process headers for( $idx = 0; $idx < count($aFrom); $idx++ ) { // get object $objData = $aFrom[ $idx ]; // get email from $strEmailFrom = $objData->mailbox . "@" . $objData->host; print_r ($strEmailFrom); // do some stuff here } // delete message //imap_delete( $hMail, $idxMsg ); } ?>
