SMTP problem [possibly OT]

[info]

Hello, thanks for your help on my previous questions. The problem I'm having now is that some users can receive mail, but cannot send mail through their clients. For example, on OE 5.5 on a Windows 98, the error message is: The connection to the server has failed Account: 'mail.hcadigital.com' Server: 'mail.hcadigital.com' Protocol: SMTP Port: 25 Secure (SSL): No Socket Error: 10051 Error number: 0x800CCC0E The relevant DNS entries for hcadigital.com are @ IN MX 10 dsl092-115-164.nyc2.dsl.speakeasy.net. mail IN A 66.92.115.164 66.92.115.164 is the IP address of the SIMS server. Server's own name is dsl092-115-164.nyc2.dsl.speakeasy.net. The hcadigital.com router entries are: <[EMAIL PROTECTED]> = hca.* = tracey = anibal = info When I look at the SIMS log in all info mode, I see no entries for the failed connection. It would appear that the client and the server never communicate. The SIMS users and accounts seem to be OK because I can send and receive through webmail. Also, this problem doesn't affect only one domain, but other virtual domains I'm hosting on the SIMS server. And, to make matters more confusing, I can send on some machines, but not others. The machine I'm personally testing is on a dialup line (no firewall). Any thoughts on what could be going on would be greatly appreciated. TIA, Anibal Escobar
