Hi Len, Cheers for the feedback - All the mail is already scanned for spam/ viruses before it hits the box and the box is a DL580 with 4 * 2GHz processors (the highest available for that version of the DL580) and we don't have the budget for a new one. The cards work out about a third the price of a new server.
For the traffic that we have (200k messages / day, 6000 unique webmail users / hour) I reckon the encryption overhead would be too do it without either an external accelerator or some internal cards. -----Original Message----- From: Len Conrad [mailto:[EMAIL PROTECTED] Sent: 15 February 2005 18:19 To: [email protected] Subject: Re: [IMail Forum] SSL / TLS Offloading Encryption >Does anyone know if the SSL encryption for the webmail components can be >offloaded to an SSL accelerator card?

These cards are pretty expensive, you need spare card(s), and you then have to see if Imail SSL/TLS can use them. I bet you will be better off in upping your server hardware to 3+ GHz CPU and fast memory w/o h/w accelerator vs a slower machine with h/w accelerator. btw, you can also save you current box but offload a ton of work to make room for the SSL stuff by running IMGate out front. IMGate always allows the Imail box to run noticeably much faster (or less stressed) and more stably than without.
