Mac Mail with a logo signature

I don't know about the latstes release, but I just made one from a jpeg. Found a sample logo, cropped it with Preview, dragged the jpeg into the window in Mail > Preferences > Signatures. Tried it with a new email and it worked.

Did just the same, I don't use signatures so I had to try it, worked just as arthur decribes.

I just tried sending myself an email with an attachment and a logo-signature.

That worked too.

They all seem to be handled as attachments. I guess I don't see the issue.

Is it a particular Windows client or do all Windows clients add it as an attachment.

There are 3 different attachment settings, one for Windows friendly, have you tried the various options?

You will find it under the Edit drop down box.

It is an attachment. It has to be. Anything in an e-mail message that is not text must be sent as an attachment. Some e-mail applications, including Mail, will display the contents of some attachments so you might not recognize that it is an attachment. What the recipient sees depends on his e-mail program, not yours.

In order for a signature logo image to work across Mail user agents, and not as an attachment, you will need the destination account to have html mail enabled. Additionally, your mail signature will need to reference your logo image on a dedicated network server.

Hi VikingOSX,

So would that also require that the system receiving the email allow a remote jpg to be opened?

regards

All of my email sources (including Exchange) are received via Mac mail. I am uniquely unqualified to comment on systems that block remote images or scan email content.

If the existing users on that system are unable to receive remote images (Amazon.co.uk Christmas deals) in their emails, then there may be a security protocol that takes precedent over remote image access in their email. It might be as simple as enabling this capability from a trusted server, or specifying a different (.png) image format.

Signature design should be done in a manner of graceful degradation to retain concise, clear textual communication in any event where the logo image is not presented to the recipient.

I am using Mavericks with the latest updates 10.9.1.

I don't use signatures so apologies if I am getting this wrong.

1. When you say signature do you mean one that was written in the signature box in Mail prefernces or a jpg file with your hand written signature on it?

2. I accecpt that if it worked under SL something has changed.

I have done some testing and if I use a jpg for the signature and add an attachment then in Apple Mail when recieved they are both treated as attachments but are displayed in the body of the email.

3. If I write a signature in the sig/prefes pane then that is plain text and only the jpg I sent is treated as an attachment but displayed in the body of the email.

This display inside the email is controlled by the Content-Disposition header before the MIME content in the email. My Apple Mail client in Mavericks sets this as 'inline', i.e.display in the body.

You can check for yourself how yours are formatted by viewing the raw source of your email, Menu Bar/View/Message and select Raw Source search for Content-Disposition and check its setting.

Now it gets a bit more interesting, it seems that Outlook mail client does not handle inline content as 'inline'

Quote.

"When you receive a message that uses the content-disposition=inline MIME type, Outlook renders the embedded content as an attachment."

see Microsoft support document http://support.microsoft.com/kb/814111

It states that this is by design.

So Apple Mail appears to be using the Content-Disposition header as by design and Outlook not, but I suppose the software designers will both disagree.

Can you check your email for Content-Disposition as online, and what do you use as a signature, plane text or jpg?

Have you any way of checking how SL formatted the same type of email, perhaps look in your older sent mails.

I may not be able to help but it would be nice to know why it is occuring.
