I have an IP Office 8.1(67) with Essential edition that won't update the time/date and SMTP isn't working either. I have 2 alarams from the system status that say : SMTP communication server failure. I have put in the correct credentials for the SMTP, but was wondering if it is because they are going through a Comcast modem/router for thier network. Could it be a blocked port? Another one says: Failed to resolver time server host name. Host name is 0.pool.ntp,org. Any ideas?
