... I did a little more research on my own, but since I'm no programmer I'd appreciate any help.
There a 2 files with the defaults disabled now and replaced by a hard coded limit:
/opt/zimbra/mailboxd/webapps/zimbra/
js/zimbraMail/mail/view/prefs/ZmSignaturesPage.
js
Line 20
Code:
this._maxEntries = 5; //appCtxt.get(ZmSetting.SIGNATURES_MAX);
/opt/zimbra/mailboxd/webapps/zimbra/
js/Preferences_all.
js
Line 10802
Code:
this._maxEntries = 5; //appCtxt.get(ZmSetting.SIGNATURES_MAX);
I modified both to the original in 5.0.18 and cleared the work cache by issuing
Code:
rm -rf /opt/zimbra/jetty/work/*
But this does not bring back the old settings either. The support case is still open with no solution. So I'll wait a little longer ...
Regards
Andreas
