[PHP-DEV] PHP 4.0 Bug #8734 Updated: Unable to send large emails, causes a GPF - small email work fine. From: wayne.cope <email protected>

Description: Unable to send large emails, causes a GPF - small email work fine.

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 !

When sending attached files (test file is only 14K), a GPF is caused by the mail() function. When the file is small (e.g. 1K) the function works fine.

I have checked the ini file settings and all seems fine, and have run the same code on version 4.0.4 and it also crashes then too. I am unable to check on any other versions. I would guess it's a similar problem to the other "malloc problem" in this section (bug report: 8360) as it would appear to be a memory issue.

Let me know if you need any more info...
