I have a Ricoh equipment which I had the scan to email feature working just fine. The internet provider is different than the email provider. A month ago, the company changed the internet provider, for a cable company. We received a preconfigured router and the cable modem. The changes in the network were minimal, including a new dns server ip address (isp dns of course). After all the configuration, performed in the network, the ricoh equipment stoped working the scan to email feature. One computer also cannot send email from the email client, but is able to receive. The other computers are working fine, but only this one is not. The error message i get from outlook is that the server denied the communication, either by the user authentication or too much time waiting to stablish the communication. The email accounts are fine, since you can use the webmail based, besides the other computers have no problems sending out. Like i said, the changes were minimail, added the dns ip address to the local server and have our router pointing the new preconfigured router. The cable company said, there is not any filtering type in their router.
Any suggestion? Hope this is not too long to read
