Re: [PHP] Mail Function In PHP
Having worked at a decent sized, respectable ISP with 100,000+ customers sending email via Iron Ports (email scanners), even they would get put on a blacklist on a monthly basis. Hell it wouldn't surprise me if Gmail's SMTP servers got put on a black list at some point. There's seemingly hundreds of blacklists and whilst some play nice, others are very paranoid. Usually the good email servers will detect your on a blacklist then rate limit the number of emails it'll accept from you. If you keep pissing it off, by sending emails to non-existant addresses (something they REALLY hate), sending emails that are too big, or simply sending too many emails or emails with too many recipients, then it'll tighten the restrictions. Over time if your good then those restrictions will be released and eventually you'll be able to send at normal rates. -- Michael Kubler I believe in a better world.

Contrary to popular belief, to send an email you do not need to have
your own SMTP server. All you need to know is the SMTP server
responsible for your recipients email.
This information is held as part of the domain registration details
and is known as the MX records (as I understand it).
PHP has a function called getmxrr() [1]. This allows you to supply a
domain name and get back the list of MX records suitable for handling
the SMTP mail.
This function wasn't available on Windows until recently, and I
created a userland version utilising Windows nslookup.exe program [2].
So, once you've got the list of SMTP servers for the domain you are
sending email to, you can use the ini_set('SMTP', 'xx'); function
to set the server to handle the mail() call you are about to make.
Upside : No local SMTP server - you are not responsible for
maintaining/administering/etc. any aspect of the SMTP process.
Upside : If the mail() call fails, you can try the other MX records (I
tend to sort the results based upon weight and try them in sequence).
If it fails all of them, you know straight away and can deal with it.
Upside : No relaying. No permission issues to worry about. You are
simply talking to the public SMTP servers just like any other SMTP
server or sender.
Downside : No queuing. Without a _LOCAL_ SMTP server, you can only
deal with sending email in real time.
Downside : One domain at a time. You cannot send email to
a...@domain1.com, b...@domain2.com _AND_ c...@domain3.com in the 1 email.
None of these steps affect the use of mail() or a mail sending class
(phpmailer, RMail, html_mime_mail5, etc.).

Richard.

Re: [PHP] Mail Function In PHP
If you control your DNS server setup and such, DKIM and authentication technologies alikes (http://en.wikipedia.org/wiki/DomainKeys) are the way to go. Also, make sure the reverse DNS lookup is pointing to the right place, i.e. that the SMTP server domain name translates to an IP that translates back to the same domain name when you do a reverse lookup. Since this is really something more of a network arch. setup, you probably will find more answers for that on ServerFault or the likes.

Re: [PHP] Mail Function In PHP
Any volume of mail sent direct to mx records is a red flag for anti spammers
and without an smtp spf dkim and rdns you are wasting your time. The logic is
that only people sending spam would be sending direct to mx like that. Fair or
not that is just how life works. Oh and most mail servers do check rdns spf
etc.
It is kind of pointless to send emails if they end up in the spam folder or
worse don't get delivered at all. Do it right the first time use an smtp rdns
and spf at the very least.

Hello, Read the manual page for the mail() function ... http://www.php.net/mail Mail() requires an operating SMTP server. This can be set in php.ini, and possibly via the ini_set() function. These might be worth looking into: $config1=ini_set(sendmail_path,/usr/sbin/sendmail -t -i); $config2=ini_set(SMTP,localhost); $config3=ini_set(smtp_port,25); If you absolutely can't run an SMTP server or use a remote server, you'd probably have to hack something together with sockets or streams.
