sendmail not working
 

I haven't been able to use sendmail. any suggestions?

am using php5 on wheezy.

tyvm.

Nope...mainly because PHP doesn't have anything to do with sendmail, unless you've written a program in PHP to use it. Since you don't provide any details, code samples, log files, or even a basic error message, there's not much we can tell you.

Try to send mail from the command line...if that works, your problem is in your PHP code. If not, post relevant details about your configuration and we can try to help

I tried to send a test mass mail using phpbb. here is a screenshot:

...which still tells us nothing. Please see the questions asked of you previously...without details, there is NOTHING anyone can tell you.

Are you sure you've configured phpBB to use your localhost for mail rather than configuring it to use an SMTP connection to another host?

If you are using a separate SMTP host then ensure that you have access to that host, are allowed to use it as a mail relay and and that if you need any form of secure connection that this has been configured properly.

Otherwise as TB0ne says, you've not really given us much to go on.

where do i find the logfiles? i tried using sendmail from bash, it locks up.i setup zend and am trying to configure it to run phpbb. i prefer to use local host, but anything that works. please be patient with the stupid guy (me). so, what's missing?

Start looking at sendmail tutorials, your mail log file is usually /var/log/maillog

Are you positive your PHP / PHPBB installation is set up to use your local mailer? From the screenshot it looks like it's trying to connect to smtp.yandex.com on port 465 which would indicate a secured connection.

the log is an empty file. the origional default settings failed, so i tried to send it through a mail account. i am not really sure about my php5 environment.

Tried to send what? and how?

So you're telling us that your sendmail itself isn't working?

i tried to send a test message. yes, thats it.
