Create an email signature in Mozilla Mail or SeaMonkey Mail
Mozilla Mail can automatically append a signature to every email you send. Unlike some email clients, Mozilla Mail lets you specify a signature per account. If you use two or more email accounts, this is a great time saver compared with hand-picking the signature depending on the occasion. 
The two hyphens and what comes below are added automatically to every outgoing email. As you can tell, Mozilla Mail supports more than plain text signatures, and actually lets you use HTML, the markup language used to create web pages like this one.
Create a Signature
First, you will need to create a file with which Mozilla Mail can work. Mozilla Mail will not accept Microsoft Word or PDF files, (even if Word files are saved as RTF, Rich Text Format.) You can create a signature in Notepad (or any plain text editor), or supply an HTML file.
For Joe Dohn's signature, we created an HTML file with the following HTML code:
To create an HTML signature in Notepad, use HTML code similar to the above, and save the file as HTML. Just replace plug in your personal data instead of Joe Dohn's. ( <br> stands for "line break" )
To attach the signature to your email account, go to Edit > Mail & Newsgroups Account Settings. Highlight the email account for which you want a signature.
Click the Choose… button, and navigate to the file you just created, and click Ok to dismiss the Account Settings dialog.
From now on, each email you send using this email account will automatically contain the content of the signature file you created.
