Hi folks, I was 99% of the way towards setting up my first email server, when I got stuck. I'm trying to setup a server on my LAN that checks for mail on my ISP using fetchmail and then forwards this to my Courier IMAP. Currently, both seem to work ok (fetchmail is giving ordinary output and connects, courier imap works if I send an email from a local account). However, it looks as if the Courier SMTP server cannot resolve any address when it does a reverse lookup. It will wait for about two minutes and then give an error message:
fetchmail : SMTP > 417 DNS lookup failure. Try again Later. What's weird is: a) I can resolve the host using the 'host' command b) I have my DNS in /etc/resolv.conf c) I have used the no dsn option in .fetchmailrc d) I have added -nodnslookup in the TCPDOPTS varible in esmptd config file. I've done some reading, and understand this might be an issue with different versions of IP, or the fact that you need two DNS servers. What was the final word on these findings? Alternatively, what configuration changes should I make to either .fetchmailrc or /usr/lib/courier/esmptd? BTW, I'm using debian and my DNS server is built-in to my D-Link router- does this matter? My .fetchmailrc looks like poll <mailserver> proto pop3 no dns no checkalias no uidl user <user> is <user> here pass <pass> pass8bits fetchall keep and this gives output like this (sorry its incomplete, but im typing it in here :) ) fetchmail: SMTP < 250 fetchmail: SMTP > ELHO localhost fetchmail: SMTP < 250 -mail OK fetchmail: SMTP < 250 -XVERP=Courier fetchmail: SMTP < 250 -XSECURITY=NONE,STARTTLS fetchmail: SMTP < 250 -PIPELINING fetchmail: SMTP < 250 -8BITMIME fetchmail: SMTP < 250 -SIZE fetchmail: SMTP < 250 -DSN fetchmail: SMTP > MAIL FROM: <[EMAIL PROTECTED]> BODY=8BITMIME SIZE=4167 fetchmail: SMTP 417 DNS Lookup failure : domain.com. Try again later. fetchmail: SMTP error : 417 DNS Lookup failure : domain.com. Try again later. fetchmail: SMTP > RSET fetchmail: SMTP < 250 OK .. not flushed and so on. Any thoughts / ideas would be greatly appreciated.
