My system is failing to send mail. I belive that I have correctly configured the $db_smtp_server to 'localhost'. The error indicates that the smtp connect () failed: Unkown error. I have looked through all the posts involving this error and I don't think I have configured anything wrongly.

Incidentaly, my links system was working and my ISP moved my site to another physical server. I have since confirmed that they have a current version of Perl installed - ActivePerl 5.6.0.613. Everything else but the smtp send is working properly.

Any help/pointers would be greatly appreciated
