Topic: Bad Header tuning

==== Required information ====
- iRedMail version: 0.8.1
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP
- Linux/BSD distribution name and version: CentOS 6.3
- Related log if you're reporting an issue:

My current setup is bouncing emails from fbo.gov because they are not putting a date field in the header.  What's the best way to let that through?  Where is that defined?  Is there a way to just globally whitelist a domain and skip all the spam checks?

It's better to paste original bounce message here to help troubleshoot.

Re: Bad Header tuning

You can find below lines in head of /etc/amavisd/amavisd.conf:

# @bypass_virus_checks_maps = (1);  # controls running of anti-virus code
# @bypass_spam_checks_maps  = (1);  # controls running of anti-spam code
# $bypass_decode_parts = 1;         # controls running of decoders&dearchivers

Please try add below line after them, then restart Amavisd service:

@bypass_header_checks_maps = (1);

It will bypass all header checks.
