Let me start with I am not a developer…I have had a request to change the font of the body of our emails to Time New Roman 11pt Plain - works well when sending to the internet and works well when sent to users hierarchical address but when addressing someone suing their smtp address instaed of their Hierarcical address the font changes to 10pt and also the HTML signature being used does not retain the same characteristics, spacing has changed slightly.
Well, let me start with “I am not an admin” – but it’s an admin issue. The changes are happening because the mail is being converted to MIME (and perhaps back to rich text). The process isn’t lossless, and it’s happening because your server(s) can’t recognize the internet address as internal.
The MIME mail that Notes sends doesn’t use absolute point sizes for text, but one of the standard HTML font sizes (1 through 7), and each size can map to several point sizes. And HTML tables? Let’s just say that Notes tries and leave it at that, shall we?
I don’t know where to find the configuration setting you need, and I don’t have a server to test with, but I’m sure you’ll be able to find it an Domino Administrator Help.
