It appears that one can use an HTML closing in iNotes if you enclose the signature in square brackets ([]). It doesn’t solve the problem of using a company logo or similar without linking to it (as opposed to embedding it in the e-mail).
Example:
[<font color="#727785" size="-2" face="Verdana, Arial, sans-serif"> <br> Med venlig hilsen, <br> <b>Mikkel Heisterberg</b><br> it-inspiration aps - farvergade 2 - 1463 copenhagen k - denmark - <br> phone: +45 7022 3141 - fax: +45 3316 0290 - mobile: +45 2682 5673 - email: <withheld><br> </font>]

Hmmm…. It appears that changing the signature in iNotes also changes the signature in Notes (which doesn’t really make sense to me). So if you do the above (html signature in square brackets) you will mess up your Notes signature.
