[OpenWrt-Devel] SStrip strange issue ?!? [Re: There is a error when I build emailrelay-nossl package in openwrt]

Hi Yangjun,

after a full check, it seems that everything is working and there is no
issue (I was wrong with sstrip). Please have a look at the video of the the
checks I have done on my router after having unistalled the libopenssl (
https://www.fededim.pw ). You can also a find a build of both emailrelay
packages (ar7xxx architecture, hoping it's the same as yours) I have used
in my test on the same website.

Finally sorry to all Openwrt folks for the fake issue on sstrip, it won't
happen again (incredibly almost half file size can be stripped).
