Can't receive mail.
« on: May 23, 2015, 10:33:30 PM »
I have been messing with system from countless hour to figure out why I can't receive mail, I have enabled DKIM and SPF , I can send mail out properly but can't receive any.

I get error from mailllog :

Code: [Select]
NOQUEUE: reject: RCPT from nm22-vm2.bullet.mail.ne1.yahoo.com[98.138.91.210]: 451 4.3.5 Server configuration error; from=<someEmailAddress@yahoo.com> to=<eti@etalkindia.com> proto=ESMTP helo=<nm22-vm2.bullet.mail.ne1.yahoo.com>
[/cod]

Same happens also when I send mail from Gmail to this server.

Tried a lots of things based of online suggestion, nothing works. Any idea what is it about ?

May be I did not explain properly,
I am using CWP 0.9.8.6

at : http://blabla:2030/index.php?module=postfix_manager

If when I enable following and rebuild mail server:   

"AntiSpam/AntiVirus (recommended): ClamAV, Amavis & Spamassassin, Requires 1Gb+ RAM"
rDNS Check (recommended):       Drop all emails if no rDNS/PTR
Install DKIM & SPF (recommended):      Installs DKIM & SPF, enables DKIM for New Accounts and Domains
Reject Unknown Hostname (NOT recommended):      WARNING: Reject unless the hostname has valid DNS record.


Then incoming mail stops working,.

I checked logs :
Code: [Select]
NOQUEUE: reject: RCPT from nm22-vm2.bullet.mail.ne1.yahoo.com[98.138.91.210]: 451 4.3.5 Server configuration error; from=<someEmailAddress@yahoo.com> to=<eti@etalkindia.com> proto=ESMTP helo=<nm22-vm2.bullet.mail.ne1.yahoo.com>
I also get mail notification about error, eg. if I try go send mail with Google :

It looks while giving details about problem I found the qcause of issue, its small bug in the entries created in /etc/postfix/main.cf

They are :
Code: [Select]
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_rbl_clientzen.spamhaus.org,reject_rbl_clientbl.spamcop.net,reject_rbl_clientdnsbl.sorbs.net,check_policy_service unix:private/spfpolicy

But should be :

Code: [Select]
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_rbl_client zen.spamhaus.org,reject_rbl_client bl.spamcop.net,reject_rbl_client dnsbl.sorbs.net,check_policy_service unix:private/spfpolicy

thanks a lot,
previously I removed all of them to have it working, see here: http://forum.centos-webpanel.com/centos-webpanel-bugs/cwp-0-9-8-6-rebuilt-mail-server-could-not-receive-send-email/msg2952/#msg2952
