Intenet Explorer 5.XX (IE5) + SSL

[Hostmaster]

Hi all,

I'm using IMP 2.2.3. When I'm not using SSL, it works very fine with IE5. But 
when i use SSL, the IMP is not stable. Sometimes i have got "DNS ERROR". 
When I use Netscape, IMP always works very fine (with or without SSL).
Somebody can help me ?

Thanks,
Jairo
