In the process of evaluating alternatives to the newly overpriced Imail software, I ran into what appears to be an explanation of this problem. The explanation I saw has nothing to do with the NIC or the operating system, but rather with the combination of the SERVER SPEED, the efficiency of the installed software on the server and the speed of the INTERNET and the receiving server.
The jist of the explanation is this: If the internet is extremely SLOW and the NIC, OPERATING SYSTEM and MAIL SERVER software are TOO FAST, then this error will occur. The VisNetic MailServer actually has a setting that allows the admin of the server to adjust the connection/wait/processing speed, in milliseconds, which is defaulted to 10 and their recommendations was that it be increased to 50 when this error occurs and never more than 80 milliseconds. This error was outlined in the documentation and FAQs for VisNetic Mailserver at: http://imageserver.deerfield.com/marcom/visnetic_mailserver/VisNetic_MailSer ver7_datasheet_letter.pdf I will try to find the original information and repost it to this forum later this afternoon or evening. Bruce Barnes ChicagoNetTech Inc PS: In spite of the fact that so many on this list are opposed to Challenge/Response (which can be totally DISABLED should the installer so desire), there are a great many features of the VisNetic Mailserver that are MUCH better than any other product we have so far reviewed. This will probably be our final choice, in spite of the initial additional costs for the product.

I just ignore them at this point. Ipswitch told me I had a "low quality NIC" and that was the problem. They said I should buy a 3com NIC. I told them they were full of it. I have dual port Intel pro server NIC on it. They have never been able to solve the problem. Great support huh? :) Wolf Tombe wrote: > Eric, > > > > Thanks for the reply to my posts regarding the Send Error 10054.
