 Posted: Sun Nov 16, 2003 8:34 pm Post subject: Can send, but not recieve mail (server) *fixed |
 |
|
I've had a mail server running for a few years, mostly without problem. Recently after an update to software, the mail server has stopped being able to recieve mail sent from non-local domains. I'm not sure which update, since the e-mail accounts on this system are rarely used, and I didn't notice anything was wrong until someone tried to send me a message and complained that it got bounced back to them.
I'm using Postfix and Courier-IMAP as is described in one of the howtos on the main gentoo site. I'm really not sure which configuration file I should be looking for an error in, and from what I can tell, they look unchanged from when the server was working properly. I can still send mail to external domains without error.
Please let me know which configuration files I should be looking for errors in, and/or posting here.

| check or post your 'RECEIVING MAIL' section in /etc/postfix/main.cf, and the settings of the variables pointed to there... |

| Try checking your master.cf file. I use Cyrus-IMAP as my LDA, and the newer version 2.x of Postfix requires a different syntax for the local transport for Cyus. Courier I am not sure of, but it's a place to start. Also, CHECK THE LOGS, they will tell you what trouble you are having (ex. name not found, no local transport available, etc). |

main.cf:
| Code: |
##RECEIVING MAIL
# The inet_interfaces parameter specifies the network interface
# addresses that this mail system receives mail on. By default,
# the software claims all active interfaces on the machine. The
# parameter also controls delivery of mail to user@[ip.address].
#
inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
mydestination = $myhostname, localhost.$mydomain, $mydomain, mail.$mydomain, www.$mydomain, ftp.$mydomain |
I don't see anything wrong with that - it all seems applicable.

I'm not sure what to think about this one.. As I said, I don't use Cyrus, but Courier instead. Any suggestions? |

Again, I would check the logs, and what kind of bounce message was it? Was it from the Postfix program? If so, postfix receiving mail is not your problem, it just isn't sure where to send it. There are a lot of steps along the way to ending up in a mailbox, somewhere it's getting dropped.
A sample of my postfix log when I give it a bogus address:
=============
Nov 17 17:35:09 animal postfix/pipe[2252]: 08229BD93: to=<none@animal.domain.com>, orig_to=<none>, relay=cyrus, delay=2, status=bounced (data format error. Command output: none: Mailbox does not exist )
=============
And the bounce message:
=============
This is the Postfix program at host animal.domain.com.
I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.
--snip--
Reporting-MTA: dns; animal.domain.com
Arrival-Date: Mon, 17 Nov 2003 17:35:06 -0800 (PST)
Final-Recipient: rfc822; none@animal.domain.com
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; data format error. Command output: none: Mailbox does not exist
=============
I don't think the bogus address is your problem, but it's an example. Start with the bounce message, then the logs, and work your way back.
About the master.cf; the courier documentation should state the proper line for the postfix local delivery in the master.cf. |

my domain is 'gleneaglemusic.net', and my ISP is telus.net .
I send a message from 'adrian@gleneaglemusic.net' to 'aroliver@telus.net' without error. I send a message from 'aroliver@telus.net' to 'adrian@gleneaglemusic.net' and after a few days, I get this message in my telus.net inbox:

*gah*
Okay, I think I found the problem.
Port 110 appears as closed on the server if I go to grc.com and run ShieldsUp.
I can't find postfix's logs.. They should be in /var/logs somewhere, right? |

On my redhat box, they are in the standard log directory /var/log, in a file named maillog.
I just sent you an email from my home mail server. I haven't received an autoreply yet, but when I do I'll see if anything seems strange.
Are you sure your DNS people (web-forward.dnsexit.com) are forwarding port 25 (SMTP) as well? |

| You want port 25 to be open, that's the smtp incoming port. 110 is pop3, that's your outgoing port and it should be blocked. |

Thx, I guess I was just getting my services confused.
25 is open (do a portscan on 'gleneaglemusic.net')
All ports of 'gleneaglemusic.net' are forwarded to the server. |

Ugh..
 /var/log/mail.log
damn thats ugly.
Okay, I fixed it. I had a setting in /etc/hosts that postfix didn't like.
 Thank you! |
