title: Mailcatcher: PHP mail() function returns false
body: <p>i will try to describe my problem:</p>
  
  <p>to debug outgoing email in local environment i installed mailcatcher (<a href="http://mailcatcher.me/">http://mailcatcher.me/</a>) but faced some problems with catching mails sent from web. if i run the script which contains only one mail() call, everything is fine and i can see the sent email in mailcatcher 127.0.0.1:1080. But when i try to access the same script from the web browser, the mail() function returns false, no any error displayed in browser, nothing in error logs. In mail log even i can see the call for mail() function.</p>
  
  <p>i am not sure, may be my nginx/php-fpm configuration is wrong, or something wrong with permissions. </p>
  
  <p>selinux is disabled.</p>
  
  <p>please help if you know the solution.</p>
  
  <p>Thanks in advance</p>
