When one of our customers receives e-mail from my users, there are images from the letterhead attached to the bottom of the e-mail - image001.gif, graycol.gif, etc. At times the entire e-mail is included in an attachment, but the text is not printed in the body of the message (you have to open the attachment to read the e-mail).
My understanding is that this happens because we are sending out e-mail in “plain text and HTML” format and they can’t read the HTML format. However, I still don’t understand why sometimes the text isn’t included in the body of the message. Shouldn’t they just see the plain text, then?
Our servers are version 6.5.1 and our clients are a mix of version 6.5.1 and version 5.10. Since I can’t reproduce this problem with any other recipients, I’m having trouble isolating the extent of it. Is there something related to using a 5.10 client on a 6.5.1 server that could cause this? Is there some sort of setting that I can use to prevent the extra graphics from being attached to the e-mail? (They are using the regular letterheads included with Notes - nothing custom.)
Any help is appreciated. Thanks.
