Hello everybody !
We have a lot of clients that have yahoo e-mails.
Yahoo accept e-mail from our server but by default sort them as spams.
What could it be? Does anyone know what does yahoo like or dislike?
If the messages are reaching the recipients' mailbox, but being sorted
as spam when they get there, it's because of their content rather than
because your server has been blacklisted or anything like that. So it's
not really a technical issue, more of a creative one - you need to find
out why your emails look like spam to the filters.
Content-Type: text/html; charset=ISO-8859-1
That's probably part of the problem. Sending in text/html only is common
among spammers, but unusual for most real mail clients which generally
default to sending multipart/alternative, with both plain text and HTML
versions, if the message is composed using HTML. Try switching to
sending multipart/alternative. Or, even better, send in text/plain when
there's no need for HTML - your message to this list had absolutely no
need to be HTML at all, as all it was was text. Only use HTML when you
have to, and when you do have to always send an alternative.
