Blocked attachments

[dhkoerber]

When attaching any file to the email I get the following
message:
553, sorry, that domian isn't allowed to be relayed
through this MTA (# 5.7.1)

and none of those email can be sent.\
I even tried Xenos Security program and chose 'unblock
all', but still can't sent messages with attachments.


Any help?

That appears to be a conflict with the domain you have defined for your
Email account and the domain your ISP uses. For example, if you have your
mail address defined to be (e-mail address removed) and you connect to domain def.com,
you likely won't be able to send mail. Many ISPs block this type of thing
so that they cannot be used as relays by SPAMmers.
