CentOs, ISP Config 3.0.3.3, from the perfect server setup. I can log in with Squirrelmail from anywhere and I can send mail from Squirrelmail to anywhere. I can ONLY receive mail from within, that is, testATkateslabDOTcom & katiijATkateslabDOTcom can send and receive to each other without problems. I can also telnet into the server and successfully send mail using an outside "from" address. Any mail sent from the outside world will not arrive, and I am not familiar enough with mail logs to be able to identify the problem. I have tried to add it as an account in Outlook, which gives me the following error (which I also get when trying to manually send mail via external telnet ): Code: Send test e-mail message: Your outgoing (SMTP) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: 451 Please try again later I have checked my dns against many online tools and it checks out OK. From reading related posts, I believe the following files hold pertinent information: Tail of maillog right after I send an email from my gmail account (it is similiar no matter the sender) Code: Aug 6 21:43:01 isp postfix/smtpd[15122]: send attr request = disconnect Aug 6 21:43:01 isp postfix/smtpd[15122]: send attr ident = smtp:69.17.24.150 Aug 6 21:43:01 isp postfix/smtpd[15122]: private/anvil: wanted attribute: status Aug 6 21:43:01 isp postfix/smtpd[15122]: input attribute name: status Aug 6 21:43:01 isp postfix/smtpd[15122]: input attribute value: 0 Aug 6 21:43:01 isp postfix/smtpd[15122]: private/anvil: wanted attribute: (list terminator) Aug 6 21:43:01 isp postfix/smtpd[15122]: input attribute name: (end) Aug 6 21:43:01 isp postfix/smtpd[15122]: disconnect from unknown[69.17.24.150] Aug 6 21:43:01 isp postfix/smtpd[15122]: master_notify: status 1 Aug 6 21:43:01 isp postfix/smtpd[15122]: connection closed Aug 6 21:43:09 isp postfix/smtpd[12596]: < unknown[209.85.220.179]: RSET Aug 6 21:43:09 isp postfix/smtpd[12596]: > unknown[209.85.220.179]: 250 2.0.0 Ok Aug 6 21:43:09 isp postfix/smtpd[12596]: < unknown[209.85.220.179]: QUIT Aug 6 21:43:09 isp postfix/smtpd[12596]: > unknown[209.85.220.179]: 221 2.0.0 Bye Aug 6 21:43:09 isp postfix/smtpd[12596]: match_hostname: unknown ~? 127.0.0.0/8 Aug 6 21:43:09 isp postfix/smtpd[12596]: match_hostaddr: 209.85.220.179 ~? 127.0.0.0/8 Aug 6 21:43:09 isp postfix/smtpd[12596]: match_hostname: unknown ~? 172.18.7.0/24 Aug 6 21:43:09 isp postfix/smtpd[12596]: match_hostaddr: 209.85.220.179 ~? 172.18.7.0/24 Aug 6 21:43:09 isp postfix/smtpd[12596]: match_list_match: unknown: no match Aug 6 21:43:09 isp postfix/smtpd[12596]: match_list_match: 209.85.220.179: no match Aug 6 21:43:09 isp postfix/smtpd[12596]: send attr request = disconnect Aug 6 21:43:09 isp postfix/smtpd[12596]: send attr ident = smtp:209.85.220.179 Aug 6 21:43:09 isp postfix/smtpd[12596]: private/anvil: wanted attribute: status Aug 6 21:43:09 isp postfix/smtpd[12596]: input attribute name: status Aug 6 21:43:09 isp postfix/smtpd[12596]: input attribute value: 0 Aug 6 21:43:09 isp postfix/smtpd[12596]: private/anvil: wanted attribute: (list terminator) Aug 6 21:43:09 isp postfix/smtpd[12596]: input attribute name: (end) Aug 6 21:43:09 isp postfix/smtpd[12596]: disconnect from unknown[209.85.220.179] Aug 6 21:43:09 isp postfix/smtpd[12596]: master_notify: status 1 Aug 6 21:43:09 isp postfix/smtpd[12596]: connection closed Aug 6 16:43:17 isp postfix/anvil[12599]: statistics: max connection rate 2/60s for (smtp:209.85.220.179) at Aug 6 16:42:57 Aug 6 16:43:17 isp postfix/anvil[12599]: statistics: max connection count 1 for (smtp:69.17.24.150) at Aug 6 16:33:48 Aug 6 16:43:17 isp postfix/anvil[12599]: statistics: max cache size 2 at Aug 6 16:42:52 master.cf most comments removed Code: # ========================================================================== # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== smtp inet n -

What happens when you send a mail from let's say gmail? Any error returned? Have you told Postfix to deliver mails to mailbox? please post /var/log/maillog

Might be a problem with your (reverse) DNS records. Check out this thread: http://tech.groups.yahoo.com/group/postfix-users/message/227202
I took a look at the thread you mentioned, but I am ashamed to admit that I am not certain how to test this theory. As I mentioned in my first post, I AM able to telnet in on port 25, from anywhere; although I can only successfull send a "telnet mail" when telnetting internally (from the same network, not just the same box). I have gone to http://www.mxtoolbox.com/SuperTool.aspx?action=mx:kateslab.com and checked MY reverse dns (for kateslab.com, the server I am having problems with) and the rDNS seems to check out OK. If I check out the IP listed as quoted above, 69.17.24.150, the rDNS checks out fine from mxtoolbox. This is what happens when I dig the IP from this box: Code: dig -x 69.17.24.150 ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-16.P1.el5 <<>> -x 69.17.24.150 ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 32877 ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 13, ADDITIONAL: 0 ;; QUESTION SECTION: ;150.24.17.69.in-addr.arpa.

Do you still have problems? It might take some time until DNS changes propagate.
Any mail coming from an External address times out. It is not automatically rejected. For example, my gmail gives me these periodically, until it finally gives up:
DNS OK- still problems According to mxlookup tool, it looks like everything is great. Still can't receive mail externally. It looks like it's timing out before being accepted by postifix. I don't know enough to begin to troubleshoot that problem. As a reminder, I CAN telnet to port 25 from inside or outside, but CAN'T send "telnet mail" from outside the network, only inside it. Thanks in advance for any help.
Yes, I am sure the mailbox exists. I can successfully log in to SquirrelMail from anywhere and view the inbox and send mail. I can successfully send and receive mail INTERNALLY, that is, to and from katiijATkateslabDOTcom and testATkateslabDOTcom. I can also successfully send mail via telnet, internally only. If I telnet in from outside the network, I get "Please try again later." vs
I will use quote boxes, so that you don't have to scroll as much. As a reminder - I can successfully SEND anywhere. main.cf (comments removed) main.cf (I have not removed the comments, as they seem to help make it easier to read) Thank you again for looking at this.
Looks ok. Your mail server is in a local network, behind a router, right? Do you have another mail server in your LAN? Is it possible that your router forwards port 25 to that other mail server instead of this one? Because I find it strange that telnet shows something different when you connet from the outside...
Progress Yes, this is behind a router. Since this is my "lab" I actually only have 2 boxes behind it, an ISP Config machine (the one that's giving me mail problems) and an Ubuntu desktop, nothing else. The router/firewall I'm using is Untangle. For testing, I turned off the firewall portion and am only using the port forwards. I was still having problems, but ! - more troubleshooting, but progress! I went into Untangle and turned off EVERYTHING except port-forwarding and I can now receive mail. I will continue to test until I can determine which module is causing the problems.
Thank you! Progress leads to more questions... Your questions have pointed me to the root of my problem. The problem is the SPAM filter built into the Untanlge firewall. It is dropping all external email - I must now contact their forum, because I have another one that is running that does not do this. However, now that I am receiving mail, I am getting this information in the logs:
Do you have ClamAV installed? If so, please check the ClamAV section in your amavisd.conf. Maybe it uses a wrong socket location or something like that. Also make sure that Clamd is running.
Solved! Thanks! My initial problem was caused by an older version of Untangle Firewall. Since the one I have been running was quite old, I just rebuilt it with the newest one. (Love VM's!) The newest version (9.1?) has default settings for the spam filter which do not interfere at all with email hosting. My secondary problem was the socket, as you mentioned. ClamAV was not configured AT ALL in amavisd.conf. Don't know why, perhaps when I updated not all settings were updated as well. Thank you again for your fresh eyes and simple suggestions. They made finding my problem far more simple than it could have been.
