Hello All
I have written script which sends mass email to around 1000 members using php/mysql. While most of them are receiving the emails, some of them are not getting it. Can someone suggest what could be the problem.
i know the email addresses of some of them. So what questions can I ask them, like server, proxy, firewall etc...
can somebody help...
thanks
That is a hard question. In my experience I have seen lots of things happen to stop emails like that. One our server was getting the time wrong in the header, another one is some email servers will stop your email if you send to the same domain too quickly. We have had to space some people out so they can get their emails. ie don@domain.com and lucy@domain.com weren't getting their emails cause the server thought it was spam. So we split them up in the list and they minute time difference did the trick. Also make sure you didn't get listed by spamcop. Seen that happen when formmail got hacked on one of our customers sites. Check your maillog and look for the particular email address to see what the error messages were.
