1. I have uncheck "quarantine bad header email" in the Global Spam Policy and Domain Spam Policy, but the bad header email still block by spam engine and enter to quarantine list. How to solve this ?
2. I want to to set the email gateway outside the iredmail. I want all email send to internet will deliver from iredmail to this email gateway and all email from internet will come from this email gateway to iredmail.
Right now I can send email to internet via gateway successfuly, but receiving still problem. When gateway pass email to iredmail, the iredmail reject with error message "Sender Address Rejected : domain not found; (the gateway hostname is mx.domain.com, so the email passed from gateway become double-bounce@mx.domain.com, and iredmail assume it is not from valid domain)
What should I set so that iredmail can receive email from gateway ?

thanks

Could you please show me the SQL records of '@.', '@[your_domain.com]' and '[user@your_domain.com]" in SQL table "amavisd.policy"? (replace [your_domain.com] by the real domain name.)

Re: Need help with bad header and email gateway

Hi Zhang,
I saw in this tabe for bad header lover is still NULL both for @ and mydomain. Eventhough I try to reapply it (check from web gui and save dan uncheck again and save), it is still NULL.
"1"    "@."    \N    "N"    \N    \N    \N    \N    \N    \N    \N    "virus-quarantine"    "spam-quarantine"    "banned-quarantine"    \N    \N    \N    \N    \N    "6"    "6"    "6"    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N
"2"    "@mydomain.com"    \N    \N    \N    \N    \N    \N    \N    \N    "Y"    "virus-quarantine"    "spam-quarantine"    "banned-quarantine"    \N    \N    \N    \N    \N    "6"    "6"    "6"    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N    \N

What should I do, change to "Y" for field bad header lover ?

Re: Need help with bad header and email gateway

Does column "policy.bypass_header_checks" has value "Y"?

Re: Need help with bad header and email gateway

hi Zhang,

It is "Y" for domain and NULL for @, but it is after I try to reapply again I didn't check before that.
Before I check the "Enable bad header checking" but uncheck "Quarantine bad header email" with this setting the bad header email still enter to Quarantine List.
Rigth now I uncheck both "Enable bad header checking" and "Quarantine bad header email", and I sent the result to you yesterday with "Y" for "policy.bypass_header_checks"
So is there any impact ?

Re: Need help with bad header and email gateway

hi Zhang,

It has been 2 days, and it seems we have no more bad header message trap to quarantine. So maybe it is because I also uncheck "enable bad header checking"

thanks
