[Dovecot] Rejected mails
I'm getting closer, now with SMTP permitted to whole of Internet to connect to my SMTP/postfix server & for my postfix server to connect out to public Internet on tcp 25 as well.
I send emails from permitted domain's SMTP servers with "Receipt Acknowledgemt" & the ack returned said it was delivered but somehow there's no mail in the mailbox & using the site below to test, it gave Rejected :
http://legacy.zoneedit.com/whois.html
OK, connected to gate1.mds.com.sg... < 220 gate1.mds.com.sg ESMTP
The recipient_id is basically a Linux OS id in my SMTP server. Would this work or I'll need to have virtual domain ids ?

In /etc/postfix/master.cf: smtp inet n - n - - smtpd -v
I just have to remove the "-v" & then restart postfix?
I'll only get to do it tomorrow as it's night time now.
Thanks Sun
When I login to take a look this morning, etc/postfix/master.cf already is non-verbose : smtp inet n - n - - smtpd
So whatever I sent previously from maillog is captured based on non-verbose.
Anything else I can provide? Should I reduce the debug_peer_level in main.cf from 2 to 1 ?

Sending outgoing emails from this dovecot/postfix server is Ok (ie emails received at destination) but incoming mails keep getting the logs below :
smtp.myportaltech.com[202.6.163.31]:25: Connection timed out Feb 21 16:37:04 hostname postfix/smtp[1381]: 8B35C200060: to=<recipient_idg@myportaltech.com>, relay=none, delay=30, delays=0.1/0.01/30/0, dsn=4.4.1, status=deferred (connect to smtp.myportaltech.com[202.6.163.31]:25: Connection timed out)
From this postfix server, if I tried doing "telnet 202.6.163.31 25" it won't respond. That is the public IP address.
If I issue "telnet private_IP_address 25" , it responds. My firewall colleague said it's not feasible to create a firewall rule from this server to its own external public address - is this a valid comment?
I'm not sure if this is the issue but I've also defined smtp.myportaltech.com in /etc/hosts to point to my server's private address but seems like smtp/postfix (or dovecot?) is still trying to connect to the external private address when it attempts to connect to smtp.myportaltech.com
Thanks Sun
Even if I'm inside the box itself & send emails to myself, it was not received too (despite that sending to external emails including gmail was Ok) :
mailx -s "tst to localhost" myunixid@localhost < /etc/hosts
mailx -s "tst to myportaltech" myunixid@myportaltech.com < /etc/hosts
mailx -s "tst to hostname" myunixid@hostname < /etc/hosts
mailx -s "tst to local private IP" myunixid@private_IP_addr < /etc/hosts

You continue to post problems with mail delivery that do not appear to be dovecot related. You are also cross posting between the Postfix forum and this one.
From what I can gleam from your posts, you have tried to make some whole sale changes in the Postfix "main.cf" and now things are messed up. Replace your custom main.cf with the default on. Restart Postfix and see what transpires. Post the results on the Postfix forum where they belong. Do not modify the main.cf with any of your custom modifications until you have first tried it. You may also have to revert to the default master.cf also.
