Ok, I've been tearing my hair out with the same problem. The offline form appears to send an email, but it never arrives. I'm running on a Windows 2003 server with php 5. 2. 25 and mysql 5. 0. 67. there is a local mail server configured using iis smtp.
I've cranked up the logging and no matter what I set the smtp host to in the department configuration (mine is set to localhost) this same strange entry appears in the mail logs each time:
2008-09-09 22:11:05 203. 23. 246. 3 OutboundConnectionResponse SMTPSVC1 ICO-4702AVIRT - 25 - - 550+This+system+is+configured+to+reject+mail+from+202. 191. 52. 83+[202. 191. 52. 83]+(DNS+reverse+lookup+failed) 0 0 107 0 531 SMTP - - - It seems the mail is being relayed via another server which makes no sense.
I use other applications on this server which make use of the localhost smtp server so I can't see how it could be an issue with the mail server config. In php. ini:
[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25
It's got me stumped. Where is the code that tells hcl how to send mail?
