mail not reaching recipient
Posted on 2010-11-08
We have web page sending e-mail to registered users,
From time to time mail is not reaching recipients, and there is no returning mail.
Usually is happens on "yahoo" kind addresses. We already contacted yahoo, but they say they don't block anything.
Anyway I guess there is some kind of black-list / spam block. Information regards user activation data - no spam;)
Now does anyone knows some practices on how to send such emails?
We are using HTML format with activation link.
I've also heard that sending mail 2'nd time may help? any advises?
