I installed a new server using the Etch Perfect Setup. I have used this guide many times before and have never encountered such a problem. Since moving to the new server lots of customers are reporting lack of confirmation emails or no reply from our customer service panel. I run an smtp server on another machine in the same datacentre and this email system is reliable. So something is wrong with my php mailer on my main server. It isn't a problem with all email destinations, just many. Can anyone suggest things to look for in the configuration files, the dns etc etc because this is a huge problem right now. Is it possible to setup php to use my authenticated smtp server on the other machine so that I don't have to change all the code for the internal php mailer?
Just to let you know that i've just changed my scripts to use my other server's smtp facility. I'd still be interested to hear ideas on what's up though.
There's nothing in the mail log because it was the php mail routine that was causing me problems. I should have clarified that the problem is solved by using smtp. But i'd still like to know what might be up with my php mail. Either there's a problem sending to some people it is being rejected.
PTR, yes. SPF, I wasn't sure on how that configured properly because I use another server for the SMTP mail for that domain.
