I can connect to the POP3 port (110) but not to the SMTP port 25. An nmap scan says that it is filtered:
Code:
Nmap scan report for mail.petrahigh.co.zw (79.170.44.54)
Host is up (0.092s latency).
rDNS record for 79.170.44.54: mail54.extendcp.co.uk
Not shown: 988 closed ports
PORT STATE SERVICE
22/tcp open ssh
25/tcp filtered smtp
110/tcp open pop3
111/tcp open rpcbind
143/tcp open imap
465/tcp open smtps
544/tcp open kshell
587/tcp open submission
993/tcp open imaps
995/tcp open pop3s
1720/tcp filtered H.323/Q.931
2105/tcp open eklogin
Nmap done: 1 IP address (1 host up) scanned in 3.07 seconds
My guess is that you can only connect to the SMTP port from specific IP addresses. Have you discussed this problem with the administrator of the server?
