Hi I am upgrading my website and have been told that with my site members having to validate their accounts via email links it would be more reliable to use SMTP rather than phpmail function. I have NO idea about mail servers! Can any mail server (I have a managed VPS) use SMTP - is it a case of installing software to use SMTP, is it in-built or are SMTP servers a different animal?? If I say 'yes' to converting my site to SMTP, what are the implications codewise for converting it from phpmail? What would I need to tell my VPS admin to do to use SMTP? As you can see I know absolutely nothing about this, so any help would be hugely appreciated. I dont want to just tell the developer to go ahead without knowing and I would like some background knowledge before I discuss it with him further. Thanks in advance for your help.
yes you can use SMTP lot's of software you can use, like sendmail, exim, etc if you using cpanel as your control panel there is a configured exim on it and you only need to configuring it to work for such as not opening open relay so any script will need to use STMP authentication for sending e-mail
