PHP mail doesn't always send

[optikalefx]

Hey guys,

 

I always get a "1" return form php mail, but with the large number of users, 10% aren't getting the email, so they are all constantly emailing me asking me help with their contact info.

 

The email address that im sending from is noreply@mydomain.com its the actual domain of the site. I'm using swfit mailer, but i've done this with just normal mail.

 

When asked about spam, some customers said it went there, but most didn't, they just never got it.

 

How can i reliably send email to my customers?

 

Thanks!

Make sure your REPLY-TO is set to the same thing as your FROM.

Thanks, just added that, still getting people that aren't getting the emails. though of course, mail returns true.

mail returns true because it is successful at submitting the email to the email queue or the smtp server. it doesn't mean that the email was received, or even sent by the server.

You need to troubleshoot and narrow down any common conditions that apply to the email addresses that A) Receive the email but put it into the junk/spam folder and B) Don't receive the email at all.

 

Are they at one or a few receiving domains? Is this constistant, any particular receiving email address always puts the email into the junk/spam folder or any particular receiving email never receives the email.

 

You should also check your sending mail server log files to determine what if any information you can find out about what your mail server did with the the specific emails that are not working or status your mail server got back from the receiving mail servers.

So obviously a lot is going wrong.  Anyone know how to understand this?
