[SOLVED] Regular expression in Whitelist

[raggoz]

Good afternoon,

If I would like to accept (whitelist) a root domain e.g. lets say *.com
What would my best approach be?
Configuration > Mail Proxy > Whitelist > add regex: *@*.com
Or use Administration > User Whitelist > add *.com

Regards, Ragnar

That depends on which part of the mail-processing you want to ignore/whitelist:

Configuration > Mail Proxy > Whitelist > add regex: *@*.com

This skips greylisting and potentially SPF lookups and RBL checks (this works only for ips not domains/regexes) on smtp-dialog level

Or use Administration > User Whitelist > add *.com

this is the user whitelist, which lets individual users decide whether a mail, which would end up in quarantine should get directly delivered - i.e. not the place for you as admin to add a domain

The third level (and maybe the one your looking for from you description) is to create a rule with fitting priority and a who-object that matches the domain and accept as action.

check out the reference documentation (also especially about the use of regular expressions since the examples you posted don't look quite right):

I hope this helps!

Hi Stoiko and thanks for your reply,

So Who-object it is thanks. The regular expression e.g. "*@*.com " seems to be working on the test cases I did.
Do you have a better solution? ;-)

this works but maybe not in the way you mean - also check your journal (`journalctl -r`) there should be quite a few warnings about the regular expression.

the regular-expression in Who-Objects are anchroed - i.e. they need to match the whole address.

I would probably write it like '.*@.*\.com'

(check out our reference manual https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmg_mailfilter_regex - or one of the excellent tutorials on regular expressions on the net)

I hope this helps!

Good afternoon, yes there were some warnings ;-)

Ok let´s try with the regex you suggested & thanks for the help.

Sounds good!

please mark the thread as 'SOLVED' - it can help others with the same questions

Thanks!

Hello, which expression can I adjust to only let mail from any domain pass to a user / group of the AD and deny the others, and to another user / group only * .cu
