Hi,
My clients are experiencing delays of 24+ hours for some emails sent via outbound.protection.outlook.com
I obtained a list of IP addresses used by outbound.protection.outlook.com by scraping the SMTP-Activity log for the past few days.
I would like to whitelist 500+ ip addresses used by *outbound.protection.outlook.com (and eventually by other provideres aswell).
1. Will this degrade performance ?
2. How can I manually insert the whole block ? I couldn't find a corresponding tab file in the ME config folder to the "SMTP Properties - Whitelist" option in the MEAdmin interface.
Thanks.
ME Greylist Whitelist bulk update
Re: ME Greylist Whitelist bulk update
For the time being I'm using wildcards ..
157.56.110.*
157.56.111.*
157.56.112.*
... etc.
157.56.110.*
157.56.111.*
157.56.112.*
... etc.

Re: ME Greylist Whitelist bulk update
Hi,
The whitelist IP's are stored in the registry. Use the reg key export as example and add the IP's that way to a .reg file and then import them:
This will have an impact on performance for the SMTP service when performing the lookups and may slow the processing of inbound emails down. I think you may want to look into upgrading to version 9. With Version 9, domains that have SPF records can now be whitelisted by MailEnable, significantly improving the effectiveness of Greylisting. What this means is that you can add the sender addresses domain to the greylisting exceptions list and will be excluded if the senders domain resolves to a valid SPF record and bypass the greylitsing.
The whitelist IP's are stored in the registry. Use the reg key export as example and add the IP's that way to a .reg file and then import them:
Code: Select all
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mail Enable\Mail Enable\Connectors\SMTP\White List]
"127.0.0.1"=dword:00000000

Re: ME Greylist Whitelist bulk update
May I ask where that setting is Ian, as we have 9 Enterprise and we are still observing such delays in receipt of emails from outlook.com in particular.
Whilst TechNet is helpful in producing a list, such as:
https://technet.microsoft.com/en-us/library/dn163583
MailEnable doesn't seem to allow CIDR form whitelist exclusions, so for .128 up to .255 we have to manually enter all of those, which is painful.
I would appreciate being guided to where to whatever setting and where it is that enables this SPF improvement to greylisting.
Thank you.

Hi,
http://www.mailenable.com/documentation ... sting.html - "Allow IP and domain exceptions to the greylisting"
The option is under the SMTP greylisting tab within the exceptions lists. If you add a domain that has an associated SPF record it will bypass the greylist check.May I ask where that setting is Ian, as we have 9 Enterprise and we are still observing such delays in receipt of emails from outlook.com in particular.

Hi Ian,
Thank you for that.
We do currently have domains in that list, but it seems those that are still Office 365 related do still encounter delays.

Hi,
Would really to know the domains and check the DNS records for the domains. Perhaps private message me the details and Ill take a look.
