Our company purchased and now using CRM premium 2011and our outgoing mail server works fine. However since we moved to new office, we began to have issues on sending E-mail. When we try use CRM to send an E-mail, the mail stays in Outbox, and it have to wait a very long time to send.
We still use the same Internet service provider(TPG in Australia) and same outgoing mail server (mail.tpg.com.au) as our outgoing mail server and same setting as before, but here comes the issue. And our IT department use Wire shark to track the packages while sending an E-mail, we find out the CRM use a different destination IP address: 188.8.131.52 which is different from the IP address the Internet service provider provide(Primary DNS server 184.108.40.206 and secondary DNS server 220.127.116.11).
Is it the DNS server setting caused this issue and could we change this setting(IP address) in CRM(because we cannot change ISPs’ DNS server address)? We make sure that there is no firewall or access control issues on out company router, but we do use Zonealarm firewall and Avast! antivirus on PC which runs CRM. Could those antivirus software cause this issue?
