PHP 4.0 Bug #4756: Mail Function Times Out. Warning Failed to Receive

From: dmullen@vis.net Operating system: Windows 2000 server PHP version: 4.0 Release Candidate 2 PHP Bug Type: Misbehaving function Bug description: Mail Function Times Out. Warning Failed to Receive I loaded PHP4 per the instructions and it does indeed operate. However when I try and use the mail() function it times out (after a few minutes) "Warning failed to receive. After multiple tries with different settings in the php.ini file I gave up and loaded PHP3 (3.0.16) and it works! I downloaded the sources (3 & 4) and went through sendmail.c for win32 and noticed a difference in the SendText(..) function there. Version 3 had \r\n when it was sending HELO, MAIL FROM, RCPT TO, and DATA commands to the SMTP server. Version 4 did not, it only had \n . I'm not sure if this is the problem but, Version 4 was making a connection to the mail server but it appeared not to be communicating properly.
