I just checked firewall. tcp/smtp(25 ) is allowed.

Any kind of DNS configuration issues....

Any pointers .....

I just executed below command

*[root@ip-173-201-189-43 tmp]# [root@ip-173-201-189-43 tmp]# telnet gmail-smtp-in.l.google.com 25 Trying 173.194.79.27... telnet: connect to address 173.194.79.27: No route to host Trying 2607:f8b0:400e:c01::1b... telnet: connect to address 2607:f8b0:400e:c01::1b: Network is unreachable [root@ip-173-201-189-43 tmp]#

Looks its a generic issue, nothing to do with mail setup.

I am not able to connect to gmail server's 25 port.

What is the work around here, any idea.....

I hope I have solved the first issue by giving right permission to /var/spool/amavisd/tmp. I gave the permission to that folder as 770.

Any input for 2nd issue.., Can it be a firewall issue...., do I need to open any port in IN or OUT interfaces...

It is strange when it logs "*very temporarily suspended: connect to alt2.gmail-smtp-in.l.google.com[2607:f8b0:4002:c04::1a]:25: Network is unreachable*".

It is just some network/dns setting causing the issue, not able to catch the issue here .., any input...

Dear All With help from you all I am now at better stage. Special thanks to Robert.

Atleast I am able to run all the required services (postfix, amavisd, clamd etc).

I sent a mail from my gmail, I received at my newly setup domain/mailbox.

I am facing issue while sending the mail outside.

From maillog I realized, two issues are there.

*1. Virus scan failed. The error log is as below *

*Mar 14 18:49:55 ip-173-201-189-43 amavis[3325]: (03325-01) (!)run_av (ClamAV-clamd) FAILED - unexpected , output="/var/spool/amavisd/tmp/amavis-20130314T184955-03325-nFS5UJ4F/parts: lstat() failed: Permission denied.

*2. Looks destination network not reachable (probably here gmail's mail server)*

Mar 14 18:49:58 ip-173-201-189-43 amavis[3325]: (03325-01) FWD from < bhanu@netcloudjobs.com> -> austin.einter@gmail.com,BODY=7BIT 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 1AE0E38A0D3E Mar 14 18:49:58 ip-173-201-189-43 postfix/error[3384]: 1AE0E38A0D3E: to=< austin.einter@gmail.com>, relay=none, delay=0.02, delays=0.01/0.01/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to alt2.gmail-smtp-in.l.google.com[2607:f8b0:4002:c04::1a]:25: Network is unreachable) Mar 14 18:49:58 ip-173-201-189-43 amavis[3325]: (03325-01) Passed CLEAN {RelayedOutbound}, MYNETS LOCAL [127.0.0.1]:46504 [127.0.0.1] < bhanu@netcloudjobs.com> -> austin.einter@gmail.com, Message-ID: < bd17726f3d35c7980426e4a55566cf79@netcloudjobs.com>, mail_id: T8Zt2QE1Eico, Hits: -1, size: 805, queued_as: 1AE0E38A0D3E, 2885 ms

Is it a dns issue. Why my mail server is saying "*delivery temporarily suspended: connect to alt2.gmail-smtp-in.l.google.com[2607:f8b0:4002:c04::1a]:25: Network is unreachable)*".

Kindly guide me to solve these 2 issues.

Best regards Austin

Some ISP's block port 25 if it is a 'home' type connection. Comcast recently started blocking and I can't connect there from home either.

configure your mail server to use your ISP's mail server as a 'smarthost', OR configure it to use an external (coloc or whatever) server as smarthost via port 587 with authentication.

Thanks Everybody I configured the relayhost entry in main.cf in /etc/postfix path as relayhost = [my service provider relay host] Thats all, I am able to send / recv email.

Next how do I make sure, my spam/antivirus filtering is working properly.... Is it that only maillog i cam check, or is there any effective way of checking it.

Thanks -Austin

Thanks John By the way I checked with my service provider. Their ISP does not block 25. But to successfully deliver SMTP mail, I need to use their relay server (it uses port 25 only).

Where will I configure their relay server . Is it in /etc/postfix/main.cfor any other file. Do I need to modify anyting in dovecot or amavisd configuration???

Thanks Austin
