Newbie Question-not sure this is where this belongs

[dsosb@]

When I log into my webmail inbox in Horde The header contains Date, From, To, Subject, Parts and Headers. All of my messages come with Download all attachments in(.zip file) in the Parts section of the ?Header. The only thing is...these emails do not have attachments added. Can anyone tell me why this is happening. And I am very sorry if I came to the worng place with this question.

Thanks very much in advance.
