Hi, I'm using squirrelmail-1.4.23-SVN stable on fedora20 and I'm noticing from the error_log the following errors that keep repeating pretty frequently: [Fri Jan 16 17:20:49.130822 2015] [:error] [pid 8752] [client 69.144.179.61:52531] PHP Notice: Undefined index: ID in /usr/share/squirrelmail/functions/mailbox_display.php on line 207, referer: https://mail.example.com/webmail/src/right_main.php?mailbox=INBOX&sort=0&startMessage=1 This repeats for ID, SUBJECT, RECEIVED_DATE_STRING, and TYPE0. It looks like this might be the result of some type of unauthorized access attempt? There are also entries like the following, which I'm not sure whether they are related: [Fri Jan 16 20:29:53.874099 2015] [:error] [pid 12039] [client 173.196.192.34:50709] PHP Notice: Uninitialized string offset: 47 in /usr/share/squirrelmail/class/mime/Rfc822Header.class.php on line 184, referer: https://mail.example.com/webmail/src/right_main.php How can I troubleshoot these further? These warnings don't seem to be impacting functionality, but I'd sure like to get them fixed. Thanks, Alex ------------------------------------------------------------------------------ New Year.
