So, I receive the mail, open it in the WebMail (in Firefox or Edge) and try to click the embedded link. This does not work, most cases a Code 404 "not found" is returned. I checked a lttle deeper and found, that the entire Link has been changed into lower case characters, even when in the original Link there were uppercase letters. E.g. DHL sends a tracking number with the link https://mailing3.dhl.de/Go/dfm4d45v7hv3szfhhtave5pptfkpzbaudrdsk8w845ht/7?t_ID=1715824557&piececode=00340434462072375354 (not a real link), then my Browser tries to open this: https://mailing3.dhl.de/go/dfm4d45v7hv3szfhhtave5pptfkpzbaudrdsk8w845ht/7?t_id=1715824557&piececode=00340434462072375354 (so, "Go" has been turned to "go" and "ID" has been changed to "id"). This issue happens in Firefox and likewise in Chrome. If I open the very link on the mobile (Android), there is no problem. So the problem is clearly on the SOGo WebMail Frontend. I am using SOGo Version 5.3.0 (@shiva2.inverse 202111250126) Any Idea what could be the reason, why the uppercase charakters are swapped to lowercase? And which instance could be responsible, Postfix or Sogo or anything else?This is an old bug (https://www.sogo.nu/bugs/view.php?id=5434).
