Allow email from adres but not all emails from a webservice.

Question

Hello, 
 There is a company (example: x) that send email to us but they are put in to quarantine. 
 This is because they are using a webservice (amazones) as middle men. 
 Is there a way to allow the email to get past the quarantine without allowing all the email from amazones to get through but only the email send by example@x.com? 
 There are no emails being blacklisted. 
 Thank you in advance!

Hi Roald, 
 To my knowledge it's not possible 
 You are right - it is kind of limited only to have "OR" options and not a "AND" option, so it is correct that just allowing *@somewebservice.com will let everything get thru with that sender address in the header, also opening from the entire amazon IP host range will allow everything from the host range thru. 
 The official documentation does not mention regex expressions in the sender address field. It's a great idea though, one that I would vote for as a feature request :-) 
 
 I found the best way for now to keep things down to a minimum, is just the allow the email address pattern thru fx. *@somewebservice,com and have a tight antispam configuration otherwise with extra RBL lists configured like : 
 ( b.barracudacentral.org - requires account ) zen.spamhaus.org ix.dnsbl.manitu.net dnsbl-1.uceprotect.net psbl.surriel.com bl.spamcop.net 
 
 Sorry I can't be of more help :-)

Hi Roald, 
 
 Yes, it should be possible under Email Protection -> SMTP ( unless you use profile mode, then look under the profile if its a localized setting or global setting ) -> Exceptions 
 You can disable anti spam checks regardless of the mail server providing the mail, by disabling all the antispam check for emails with " these sender addresses " aka x@somewebservice.com 
 It would be recommended to leave the antivirus active. 
 
 Hope it helps
