Hi. I know this kind of question comes up a lot but I've been through all of them and can't for the life of me see why I'm having problems with my setup. I have installed and configured postfix / dovecot and am able to send messages directly from the server. I am now trying to configure an email client (Mail). I can login to the server via port 143 and retrieve messages from my inbox. However I cannot connect to the server to send an email. I've opened up port 26 in the firewall as my ISP has blocked this. I'm able to telnet to port 26 on my mail server from a remote machine and can connect. netstat -tap shows the following: tcp 0 0 *:smtp *:* LISTEN 10661/master tcp 0 0 *:26 *:* LISTEN 10661/master iptables --list shows: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:mysql ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT tcp -- anywhere anywhere tcp dpt:26 ACCEPT tcp -- anywhere anywhere tcp dpts:ftp-data:ftp ACCEPT tcp -- anywhere anywhere tcp dpts:50000:50050 ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:imap ACCEPT tcp -- anywhere anywhere tcp dpt:imaps ACCEPT tcp -- anywhere anywhere tcp dptop3 ACCEPT tcp -- anywhere anywhere tcp dptop3s ACCEPT tcp -- anywhere anywhere tcp dpt:ndmp ACCEPT all -- localhost anywhere ACCEPT icmp -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state NEW,RELATED,ESTABLISHED REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state NEW,RELATED,ESTABLISHED As you can tell this is the first time I've set up a mail server from scratch and am going round in circles now - I am so close but just need a bit of advice from any gurus out there who've had this problem before. Many Thanks
- Are you authenticating yourself when you want to send mail? - "tail -f" the mail log files and watch for entries when you try to send mail and see if you find any error messages.
thanks for responding so quickly! am seeing Aug 15 11:04:43 BrightEdgeWeb postfix/anvil[12950]: statistics: max connection rate 2/60s for (26:78.86.227.26) at Aug 15 10:58:03 Aug 15 11:04:43 BrightEdgeWeb postfix/anvil[12950]: statistics: max connection count 1 for (26:78.86.227.26) at Aug 15 10:57:59 Aug 15 11:04:43 BrightEdgeWeb postfix/anvil[12950]: statistics: max cache size 1 at Aug 15 10:57:59 Aug 15 11:07:46 BrightEdgeWeb postfix/smtpd[13269]: connect from 78-86-227-26.zone2.bethere.co.uk[78.86.227.26] Aug 15 11:07:46 BrightEdgeWeb postfix/smtpd[13269]: lost connection after EHLO from 78-86-227-26.zone2.bethere.co.uk[78.86.227.26] Aug 15 11:07:46 BrightEdgeWeb postfix/smtpd[13269]: disconnect from 78-86-227-26.zone2.bethere.co.uk[78.86.227.26] Aug 15 11:11:06 BrightEdgeWeb postfix/anvil[13271]: statistics: max connection rate 1/60s for (26:78.86.227.26) at Aug 15 11:07:46 Aug 15 11:11:06 BrightEdgeWeb postfix/anvil[13271]: statistics: max connection count 1 for (26:78.86.227.26) at Aug 15 11:07:46 Aug 15 11:11:06 BrightEdgeWeb postfix/anvil[13271]: statistics: max cache size 1 at Aug 15 11:07:46 does that mean anything?

Looks good. What error messages do you get in your email client and in the mail log? What's in your master.cf?
