Hi, I cannot send or receive mail to/from specific address. Lets say I have: domain1.tld domain2.tld Servers: DNS Server, Web Serrver, Mail Serrver They both hosted on the same DNS Server and Web Server. For email: domain1.tld hosted at Mail Server, but domain2.tld hosted outside (Rackspace mail). All domains can send & receive mail from Google & Yahoo, but cannot send/received between them. I checked mail.log why it said "relay=dovecot" without IP information, isn't it means that mail only sent to localhost ? This is mail.log when I send mail to my gmail:
@Croydon I'm sorry the '[email protected]' it should be named '[email protected]' and the email is hosted outside (Rackspace mail). The log said 'status=sent (delivered via dovecot service)' but mail never arrived at rackspace mail box. On the contrary, mail sent from rackspace also never arrived on my ispconfig mail box. Why the log said it delivered to local when the [email protected] mailbox is hosted outside (rackspace) ? UPDATE: The mail finally arrived after more than 12 hours. What causing this delay ? postgrey ? I also whitelisted '[email protected]' on Global Filters >> Postfix Whitelist. I just retry to send mail from both side now. Mail from rackspace now arrived in 2 minutes. Mail from my ispconfig still hasn't arrived. Is this normal in very low mail box usage (almost no mail traffic) ?
Have you checked, if you have accidently defined the domain2.tld in maildomains in ISPConfig? If yes, the server tries to deliver locally as with setting a mail domain you tell the server that he shall be the target for those mail.
Yes, thanks @Croydon . After checking my mail server it turns out that my mail server still has that domain2.tld even I had removed it from my master server. I think it solved the mail sending problem, now I can send mail to domain2.tld. I'm worried if it has syncing issue between my master server and mail server. So for testing, I added a new mail domain from master server, then use Tools >> Resync . I login to mail server, check it had not been synced. I have to wait almost 10 minutes before it finally synced. Then I add a new mail box from master server , use resync, and check mail server, still not sync. Now after more than 15 minutes, it still hasnt synced yet and it still hasnt synced after ~10 minutes more before I submited this post. FYI: I already add ip and hostname to /etc/hosts on both servers. On maister server I add 'IP_ADDRESS mx.mailserver.tld mx' and on mail server I added 'IP_ADDRESS master.server.tld master'. Latency between master server and mail server is around ~180ms. How speed up sync between servers ?
It doesn't seem to me that this is a speed issue. Maybe there is something wrong with the ispconfig installation on the slave server. Have you checked enabling the debug mode and running the ispconfig server cron job by hand?
I tried to run '/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done' and it never stop so I check syslog.
