This PHP function working just fine:
if (preg_match ("/<(\S+@\S+\w)>.*\n?.*55[0-9]/i",$body,$match)) {
echo "found!";
}
in
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
[email protected]
SMTP error from remote mail server after RCPT TO:<[email protected]>:
host mx3.hotmail.com [65.54.188.72]: 550 Requested action not taken:
mailbox unavailable
But if I use the same php function in this case:
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
[email protected]
SMTP error from remote mail server after end of data:
host d.mx.mail.yahoo.com [209.191.88.254]: 554 delivery error:
dd This user doesn't have a yahoo.com account ([email protected]) [0] - mta1010.mail.mud.yahoo.com
The preg_match function does not give any results. What am I doing wrong?
You are basically looking for a email addressing enclosed in < and >.
Your first input has it but the second input does not: It has no email id in < > hence you don't get a match.
Edit: (after your comment):
Looking at the 2 samples given by you the email id appears between the string failed: and the error code starting with 55. You can make use of the preg_match for this as:
if(preg_match('/failed:.*?(\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b).*55[\d]/is',$str,$m)) {
echo "Bounced email ".$m[1]."\n";
}
