Hello Team,

We have observed that the email signature consists of social networking sites like Facebook,Twitter etc.,  are redirecting to the other link because customers IT teams use a rewrite for any URLs in an incoming email.: 
 
Example Facebook:
https://protect-us.mimecast.com/s/KVFrCERpm5tlM98MiPsxzJ?domain=facebook.com

So, these url’s going through multiple layers which might be due to permission or security reasons from the customer end and during that process a large number of hyperlinks are converted into Text which causing the space issue.
 
Please consider this as an enhancement and to ignore the hyperlinks in the emails content.
