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.

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', 'xxxxxx'); 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.).
Regards,
Richard.

Hello everyone,
I'm writing a class to send mail via an SMTP server with authorization.
Everything seems to work but I get an EHLO error:
554 SMTP synchronization error
Where should I look to avoid this?
Thanks!

Be polite :-D
Make sure your class waits for the other server's greeting
before you send HELO/EHLO. ;-)

You can use SNI, but it's not supported by all web servers and browsers.

Maybe slightly less painfull, you can always write your own 'mimemagic'
detection method. The magic.mime file is relatively easy to parse. This
is the route we took some years ago to make our mime detection OS
independant. We've made a php script which parses the mime.types file
and the magic.mime file and it generates a php module which uses that
information to figure out the correct mimetype.
The resulting php module has a large array, which looks like this:
...
$mimemagic_data[0][4]["\0\0\1\273"]="video/mpeg";
$mimemagic_data[0][4]["\0\0\2\0"]="application/x-123";
$mimemagic_data[0][4]["\0\0\32\0"]="application/x-123";
$mimemagic_data[0][4]["\0\6\25\141"]="application/x-dbm";
$mimemagic_data[0][4]["\101\104\111\106"]="audio/X-HX-AAC-ADIF";
$mimemagic_data[0][4]["\103\120\103\262"]="image/x-cpi";
...
with the first key as the offset to start, the next key is the length of
the snippet to check (I guess that could have been skipped...) and the
final key is the exact string to match.
The magic.mime file is no magic bullet though, there are occasions when
it won't match with a file, but that's usually with more complex types
like microsoft office documents, not with images.
If you're interested, the mimemagic module can be found here:
http://svn.muze.nl/trunk/lib/modules/mod_mimemagic.php?revision=4299&root=ariadne-php5
And the builder script (which you should run on a unix system with
magic.mime and mime.types file) is here:
http://svn.muze.nl/trunk/bin/utils/build_mimemagic_script.php?revision=4299&root=ariadne-php5
Hope this helps,

Hello List,
I am using the math function exp( $arg )
http://php.net/exp
... using argument values ranging between 0 to 1500.
When I get into larger numbers, such as 750, the function returns an
undocumented "INF".
Presumably the "INF" means the number exceeds processing capacity. It would
be nice to know the official explanation.
At any rate, I want to capture the "INF" so that I can indicate to my users,
in a friendlier manner, that capacity is exceeded.
How?
Please also cc my address on your reply, with thanks,
Sincerely,
Esteban

You can use the is_infinite() function. It's not entirely undocumented
though. See http://php.net/float. Basically you'll get INF when you
exceed the range according to the IEEE floating point standard.
