Hi All ,
A little teaser for you . I have UPC 15mb and it works fine , no issues with disconnections etc... which is great .... But...
I have a WiFi camera which is configured to send me alerts when motion is detected. I setup the mail side with the proper parameters smtp.upcmail.ie and used a random senders address (firstname.lastname@example.org). I dont own that account , but as I amnt going to be recieveing mail it shouldnt be an issue. I had to turn off the Firewall on the Cisco box as it was blocking Port 25 outgoing. This worked great for 1 day , I got alerts etc.... , then it stopped sending them. I have since setup a mail account using thunderbird , again using a random address and this wont send either. It gets as far as saying connected to smtp.upcmail.ie and then says mail server rejected the sender .
I rang UPC and they denied that they block mail or ports .
So , anyone got any bright ideas ?
