Topic: How to whitelist IP range

==== Required information ====
- iRedMail version (check /etc/iredmail-release):
- Linux/BSD distribution name and version:
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):
- Web server (Apache or Nginx):
- Manage mail accounts with iRedAdmin-Pro?
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

Hi,

I would like to ask if how does whitelisting of IP range can be done. We have a salesforce account in our company which uses about 30 different IP's and are getting blocked.

Tried doing test email deliverability in Salesforce to a certain email, salesforce sends 30 emails to that user coming from 15 different IP's and all are blocked in the first attempt as can be seen in the logs.

Any idea how can this be done.

We are using 0.9.5-1

Thanks,
NNN

Re: How to whitelist IP range

- Could you please show us related log in Postfix log file?

Re: How to whitelist IP range

Try this:

cd /opt/iredapd/tools/
python spf_to_greylist_whitelists.py --submit 'salesforce.com'

Then it should be fine.

if you're running iRedAdmin-Pro, you can whitelist domain 'salesforce.com' for greylisting service in iRedAdmin-Pro directly: System -> Anti Spam -> Greylisting, then add domain 'salesforce.com'. It may take 10-30 minutes - depends on the cron job which runs script '/opt/iredapd/tools/spf_to_greylist_whitelists.py'.

Re: How to whitelist IP range

Hi Zhang,

I haven't yet run what you suggested.

However, when I run it without argument as suggested when I read the content of that script, salesforce.com is already there.

$ python spf_to_greylist_whitelists.py

Thanks

Re: How to whitelist IP range

Run command without '--submit', but add a new one: --debug:

python spf_to_greylist_whitelists.py --debug 'salesforce.com'

It will list all allowed mail server IP addresses for mail domain 'salesforce.com'. Is the rejected IPs listed there?

I think this is salesforge's mistake that they didn't list these IP addresses/networks in their SPF record.

The only one SPF syntax missed by iRedAPD is the "exists:%{i}._spf.corp.salesforce.com", but i queried it manually, it doesn't contain the missed IP addresses either.

dig -t a 136.146.128.64._spf.corp.salesforce.com
dig -t a 64.128.146.136._spf.corp.salesforce.com

FYI:

- SPF DNS record syntax: http://www.openspf.org/SPF_Record_Syntax#exists
- Macros in SPF DNS record syntax: http://www.openspf.org/RFC_4408#macros

Please try to contact salesforge mail server admin to update the SPF DNS record.

Currently, you have to whitelist these addresses manually with iRedAdmin-Pro, or if you prefer command line tool - /opt/iredapd/tools/greylisting_admin.py.

cd /opt/iredapd/tools/
python greylisting_admin.py --disable --from '136.146.128.64'
