BT Internet E-Mail Blocking

Hi,

We seem to have an issue whereby BTInternet E-Mail accounts on the company firewall are being blocked.

This is NOT a port blocking issue. As other IMAP/POP services work, I therefor believe BT are blocking our office IP. As hotspot it works fine etc.

 

When doing a packet capture: (removed my public IP for now)

15 2022-05-20 10:30:02.295664 213.120.69.1 110 x.x.x.x POP 50439 74 S: -ERR Access denied

16 2022-05-20 10:30:02.295689 213.120.69.1 110 x.x.x.x TCP 50439 60 110 → 50439 [FIN, ACK] Seq=239 Ack=51 Win=23040 Len=0

17 2022-05-20 10:30:02.297503 x.x.x.x 50439 213.120.69.1 TCP 110 54 50439 → 110 [ACK] Seq=51 Ack=240 Win=131072 Len=0

 

Who can I email these details over to so they can get this looked into?
