This guide will walk you through configuring Samba/CIFS shares on your Ubuntu (12.04) server. If all goes well, your Windows computers (as well as Macs) will be able to connect without issue. This guide has steps on how steps on how to set it up in the Desktop and in shell (ubuntu server). You do not need to do both.
Some knowledge of HTML is required for adding images in HTML signatures. You will need to upload the image to a server somewhere (preferably yours) and prepare a link. Also, these email signatures do not carry between each Webmail option in cPanel or email clients.
Example: <img src=”http://domain.com/images/picture.jpg” />
To turn on HTML signatures, click on “Settings” in the upper right hand corner, then click the “Identities” tab. Select the email address on the left side. Select the Signature tab and click “HTML Signature”. From here, you can add the HTML necessary to display your images. Note, however, that HTML for the entire email is disabled by default and would have to be enabled for each message you compose. To force full HTML email for every message you compose, click on the “Preferences” tab, then “Composing Messages”. Next to “Compose HTML Messages”, in the drop down select “always”, then save.
– Signatures don’t automatically add at the end of a new email?
Settings > Preferences > Composing Messages > under “Signature Options”
Check to see if “Automatically add signature” is set to “always”.
SquirrelMail & Horde
Unfortunately, the other two Webmail applications at the time of this writing do not support HTML signatures, let alone HTML emails. Both support regular signatures but not HTML.
So if you insist on using HTML for your email signature, Roundcube is the (only) way to go. An even better solution would be to use your own email client.
