Also, you can and should carefully inspect your mail logs related to the send. You will be able to count the number of outgoing messages and match them to the original message's recipients. > We have the address book setup in the following manner; > > A-C staff > D-I staff > etc > when she sends to all entries a-z * with an attachment* this happens. Depending on how many recipients are on the message, you can definitely run into limits, not the least of which is the HTTP POST size limit. > It NEVER happens when she does not attach an Word document. Then my guess is that it's a matter of trying to send too much data over a HTTP POST. There is no workaround for this other than to modify how such messages are sent (by the user). You can test my theory by duplicating the outgoing message and dumping the $_POST variable in compose.php (use "sm_print_r($_POST); exit;") when you click send or maybe by using some browser plugins that can monitor POST data, etc. > I have tried to get the secretaries to use the mailman setup I have had > setup but teachers are generally narrow minded and want s the email in > their own inbox:(.Its a long story not worth explaining. > Even at that this has not happened till this year when a few more teachers > were entered in the global address book of Squirrelmail -- Paul Lesniewski SquirrelMail Team Please support Open Source Software by donating to SquirrelMail! http://squirrelmail.org/donate_paul_lesniewski.php ------------------------------------------------------------------------------ Come build with us!
