ok I haven't really changed anything but some more time has passed since my last post and now it seems like *google* doesn't appear in the logs anymore. on the other hand I keep seeing connection timed out like this: Jul 13 07:25:09 domU-12-31-39-00-5D-07 postfix/smtp[25866]: connect to mail.mydomain.com[75.101.163.xx]: Connection timed out (port 25) and im still seeing example.com Jul 13 07:27:06 domU-12-31-39-00-5D-07 postfix/smtp[25878]: ABB62F432E: to=<[email protected]>, relay=none, delay=330408, delays=330378/0.03/30/0, dsn=4.4.1, status=deferred (connect to example.com[208.77.188.166]: Connection timed out) Jul 13 07:27:06 domU-12-31-39-00-5D-07 postfix/smtp[25878]: connect to example.com[208.77.188.166]: Connection timed out (port 25) and im still seeing Jul 13 07:22:46 domU-12-31-39-00-5D-07 imapd: chdir mydomain.com/sales/: No such file or directory and it looks like something is queued somewhere Jul 13 07:26:36 domU-12-31-39-00-5D-07 postfix/qmgr[23628]: ABB62F432E: from=<[email protected]>, size=1050, nrcpt=1 (queue active) also, if i go to http://mail.mydomain.com, on one computer i get a 404 "server not found error" and from another computer i see the "Apache 2 Test Page". somebody asked me this "is your amavis giving back the mail not on localhost and the port is just bound to localhost?" and said to check /etc/postfix/master.cf and amavisd.conf but I didn't really understand what I'm supposed to change =/ and somebody else said "Sounds like a firewall/port 25 block to me"... I did follow this guide http://www.crypt.gen.nz/selinux/disable_selinux.html and disabled selinux like you said in the beginning of the guide. [root@domU-12-31-39-00-5D-07 selinux]# cat /selinux/enforce 0[root@domU-12-31-39-00-5D-07 selinux]# here is the output of "iptables -L": also when i "telnet localhost 25" it works fine, but if i do it remotely, i get connection refused =/ finally, i've sent a new email from gmail and another provider to [email protected] and this time it took 50 minutes to bounce back.
here is the new log: wow the email bounced back from my setup and not from gmail this time... this the email i got: from Mail Delivery System <[email protected]> to [email protected] date Mon, Jul 13, 2009 at 1:10 PM subject Undelivered Mail Returned to Sender hide details 1:10 PM (5 minutes ago) Reply Follow up message This is the mail system at host mydomain.com.

its already there.. maybe im missing something. the server is setup on amazon ec2... if i dns mail.mydomain.com i get 75.101.163.xx, if i reverse dns that ip i get something like ec2-75-101-163-xx.compute-1.amazonaws.com and the internal hostname is domU-12-31-39-00-xx.compute-1.internal ... i've tried adding everything to mydestination: mydestination = mail.mydomain.com, localhost, localhost.localdomain, 75.101.163.xx, ec2-75-101-163-xx.compute-1.amazonaws.com, compute-1.amazonaws.com, amazonaws.com, 127.0.0.1, 127.0.0.0, domU-12-31-39-00-xx.compute-1.internal, compute-1.internal If i add mydomain.com in there, I get: warning: do not list domain mydomain.com in BOTH mydestination and virtual_mailbox_domains is it normal that my /etc/hosts only has 127.0.0.1 localhost localhost.localdomain i think my internal hostname may also be domU-12-31-39-00-xx-xx.compute-1.internal, should i add that to /etc/hosts ? here is my current error log: and here is the current postconf -n I can see the messages getting queued up in the mail log, if i do "postqueue -p" i can see them, so it means its somewhere on the server but it keeps looping around
i added "75.101.163.xx ec2-75-101-163-xx.compute-1.amazonaws.com" to /etc/hosts and now this warning is gone: domU-12-31-39-00-5D-07 postfix/smtpd[2641]: warning: 75.101.163.xx: address not listed for hostname ec2-75-101-163-24.compute-1.amazonaws.com but this is still happening: Jul 15 10:28:40 domU-12-31-39-00-5D-07 postfix/smtp[6233]: warning: host mail.mydomain.com[75.101.163.xx]:25 greeted me with my own hostname mydomain.com Jul 15 10:28:40 domU-12-31-39-00-5D-07 postfix/smtp[6233]: warning: host mail.mydomain.com[75.101.163.xx]:25 replied to HELO/EHLO with my own hostname mydomain.com Jul 15 10:28:40 domU-12-31-39-00-5D-07 postfix/smtp[6233]: B52E4F4283: to=<[email protected]>, relay=mail.mydomain.com[75.101.163.xx]:25, delay=0.13, delays=0.05/0.02/0.07/0, dsn=5.4.6, status=bounced (mail for mail.mydomain.com loops back to myself) here is /etc/hosts here are the MySQL tables... maybe I made a mistake there.. mysql> select * from domains; +-------------------+ | domain | +-------------------+ | mydomain.com | +-------------------+ mysql> select * from forwardings; +------------------------+-------------------------+ | source | destination | +------------------------+-------------------------+ | [email protected] | [email protected] | +------------------------+-------------------------+ mysql> select * from transport; +-------------------+-----------------------------+ | domain | transport | +-------------------+-----------------------------+ | mydomain.com | smtp:mail.mydomain.com | +-------------------+-----------------------------+ mysql> select * from users; +-------------------------+---------------+----------+ | email | password | quot a | +-------------------------+---------------+----------+ | [email protected] | 4e3wiBPp/SJGk | 10485760| +-------------------------+---------------+----------+
hmmm.. same exact error.. I thought maybe MX records are wrong but they also seem ok: mail.mydomain.com A 75.101.xxx.xx 3600 mydomain.com MX mail.mydomain.com 10 3600 Also, I saw someone mentioned to look at /var/log/messages in one of the forums.. I see this: Jul 16 10:37:08 collectd[22625]: uc_update: Value too old: name = i-a38ea4ca/df/df-mnt; value time = 1247755028; last cache update = 1247755028; It's happening everything 10 seconds but I don't think it has anything to do with the mailing problem... I really don't understand what is wrong I even started a new installation from scratch on my ns2 server using this guide: http://wiki.centos.org/HowTos/postfix (no virtual domains) just to check if there is some strange problem with the server. I am able to receive email to user "john" and I can read it. Everything works. I turned off ns2, made it into ns1. My postconf -n for that server is btw I am trying to do the following setup: lets say i own mydomain.com and want to be able to send mail to @subdomain1.mydomain.com and @subdomain2.mydomain.com with virtual accounts... so far I was only testing @mydomain.com and that hasn't worked yet ok i think im gonna give up on this setup. I was able to set it up without mysql in there so quickly using postfix.org's virtual readme page...
