 Posted: Thu May 27, 2004 11:40 pm Post subject: qmail accepting connections from localhost only |
 |
|
I am using this guide in setting up qmail. I'm not quite sure I've completely gotten the way DJB thinks yet, so I'm a little out of my territory here. I suppose it's possible my ISP recently blocked incoming port 25, but this was working with postfix a week ago before I re-installed.
Basically, it seems to run fine from localhost: | Code: | fw qmail # telnet 68.66.197.222 25
Trying 68.66.197.222...
Connected to 68.66.197.222.
Escape character is '^]'.
220 localhost ESMTP |
I can type in the commands and send a piece of mail. But I can't for the life of me connect to it from the outside world. Here's a copy of my /etc/tcp.smtp:
| Code: | # Qmail-Scanner disabled for mail from localhost, relay allowed
127.0.0.1:allow,RELAYCLIENT="",RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/qmail-queue"
# Qmail-Scanner enabled (virus only) for mail from local network, relay allowed
192.168.1.:allow,RELAYCLIENT="",RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl"
# Qmail-Scanner enabled (virus and spam) for mail from external internet, relay denied
:allow,QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl" |
I'm not sure where else to look. Heck, I'm not even sure which configuration file to look in at this point. I was thinking of unmerging qmail and trying postfix to verify my ISP hasn't blocked incoming smtp, but it sounds like a pain in the neck what with the whole circus you gotta go through to get qmail installed in the first place. Maybe I'm over-thinking it?
| Code: | Z:\>telnet 68.66.197.222 25
Connecting To 68.66.197.222...Could not open a connection to host on port 25 : Connect failed |
Thanks for any help.

| Did you edit tcp.dmtp, I can't remember what it looks like in the default install. If you did, did you rebuild the binary database? |

If by tcp.dmtp you mean tcp.smtp, then yes, read the above what I quoted, those are the only lines in the file.
To rebuild the binary database, I did this: (from the above mentioned guide)
| Code: | tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp
chmod 644 /etc/tcp.smtp* |

Is that still your IP address? Without meaning to be rude I've just telnetted ok to 25 on that. I guess you've fixed it?
| Code: | Trying 68.66.197.222...
Connected to 68.66.197.222.
Escape character is '^]'.
220 localhost ESMTP
HELO
250 localhost
quit
221 localhost
Connection closed by foreign host.

you fixed it!! 
I have no idea what changed, I haven't touched anything for a couple days now.
Maybe my work is blocking outbound 25, giving me false negatives when testing. Anyways, time to turn iptables back on =p thanks for your time Spooky Ghost.
