Re: [IMail Forum] Time Out Period on Web Mail on Tuesday 3:54:04 PM
You comment that Imail tries to remember HTTP status. I would
presume this is for security... logout upon a period of inactivity..
This was one of my first thoughts was that perhaps Imail was logging
me out during the transfer, which is why I wondered if there was a
way to extend this...thus my question. The contradiction was that I
could still use the web mail. I see FTP instances in TCP/IP, so it
appears you are using FTP to transfer attachments in webmail. Maybe
this is really a matter of FTP timeout?
