Description

Using only a html version of a domain-wide-footer results in the domain-wide-footer not attaching from some email clients. Meanwhile all works as expected from sogo webmail. 

Adding a plain text version of the domain-wide-footer works as expected from all clients and sogo webmail.

The mailcow UI configuration page does not give instruction to add both a html and plain text version of the domain-wide-footer.

Steps to reproduce:

1. add an html version of a domain-wide-footer
2. leave the plain text version of the domain-wide-footer blank
3. send an email using an IMAP email client and the domain-wide-footer does not attach

** variations on this
macOS Mail without a user signature = no html domain-wide-footer attached BUT with a user signature the domain-wide-footer DOES attach. 
iOS Mail app does not add the html domain-wide-footer with or without a footer. 
Thunderbird on MacOS does not add the html domain-wide-footer with or without a user footer.

All of the above is repeatable with or without a smtp relay.

Hi,

I'had same issue. Using Thunderbird, thought I've marked "Write in HTML format", for some reason the mail is parsed as plain text.

Workaround: Stablish each Thunderbird client to add a "fake" signature in HTML (for example write <b></b> or some other HTML tag in the field).
Second workaround: make sure the client is redacting in HTML, and at the moment of redacting a new email, select a word and mark it as "bold" to generate some HTML tagging in the body of the message.

Best regards
