Bug #8734 Updated: Unable to send large emails, causes a GPF - small email work fine.

ID: 8734 Updated by: wayne.cope@sitel.co.uk Reported By: wayne.cope@sitel.co.uk Status: Duplicate Bug Type: Mail related Operating System: Windows NT 4 PHP Version: 4.0.4pl1 Assigned To: hholzgra New Comment: No, this has not been changed in 4.1.2. I have downloaded the source code for release 4.1.2 and the buffer used for sending mail is still hardcoded to 4K, and so still causes a GPF when trying to send an email larger than 4K (a buffer very easily broken by sending attachments for example).

You need to change the line #define MAIL_BUFFER_SIZE (1024*4) /* 4k buffer */ to #define MAIL_BUFFER_SIZE (1024*1024) /* 1Mb buffer */ in file "sendmail.h" to make this function work. Ideally, the buffer size should be calculated dynamically, but that'll take a bit longer of course ! Can someone try and pop this change into the next release please. TTFN ! Wayne Cope ------------------------------------------------------------------------ [2001-01-16 08:25:58] wayne.cope@sitel.co.uk I have checked the source code for the Windows version of the mail() function and have determined that there is a 4K limit to the mail buffer - which is nowhere near enough. The line is: #define MAIL_BUFFER_SIZE (1024*4) /* 4k buffer */ Which can be found in "sendmail.h" under the Win32 compilation. I can't compile the code to check for sure, but it does look like this is the problem. C'ya !
