Hi Roger

Many ISP's and hosting providers are now insisting that their customers configure their email client or their PHP scripts to send email using SMTP protocols.

SMTP is a method of securely sending email and being able to clearly identify the sender, rather than being able to anonymously send emails - which is sent using POP3 - this is the case.

Obviously without the ability to send anonymous emails is a deterrent against spammers - and if the ISP or hosting provider insists on only STMP sendmail, this means theres a lot less chance of them (the ISP or host) being blacklisted.

This then forces uses of scripts (particularly PHP) to ensure that any email the script sends out, such as replies to support tickets, signup confirmation emails - anything - is sent using STMP - so any script which doesn't have SMTP capabilities, and probably is only configured to send out emails by POP3 - simply won't send out emails.

Even scripts which did work previously will simply stop working if the host switches over to SMPTP only.

I know there are lots of helpdesk / support ticket scripts out there, but not sure which of them are set up with SMTP.

Hope that makes sense.

Kindest regards

Gary
