our customers are complaining that they are not receiving invoices but i can see email logs in messages. is there a way to figure out why they are not receiving them?

There's been talk about this on Reddit. O365. https://www.reddit.com/r/Netsuite/comments/mlhjky/outlook_365_users_not_receiving_pdf_attachments/

if it is not being bounced, then its on their mail server... its typically a masking problem where their software is detecting the email is coming from

@netsuite

being being masked as coming from

@yourcompany

which it detects as bad

is there a solution to this cause this is causing too many issues for us

they prob need to whitelist

@netsuite

on their mail server or you need to find a way to stop masking emails sent from netsuite and have them send as

<mailto:yourcompanyname@netsuite.com|yourcompanyname@netsuite.com>

so their mail servers dont think it is spam/fraudulent
