Mail relay account constantly getting blocked
Hi there, We had set up an Office 365 mail account to use for mail relay task like MFD (copier, scanner) to do "scan to email". However every now and then the account will be blocked in Office 36...
There are a few options to relay messages from internal systems/devices through Exchange Online https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-office-3
We have done it with an internal SMTP, which has a connector with Exchange Online, as described here http://www.expta.com/2013/10/how-to-configure-internal-smtp-relay.html or officially https://docs.microsoft.com/lt-lt/Exchange/mail-flow-best-practices/how-to-configure-iis-for-relay-with-office-365?redirectSourcePath=%252fen-us%252farticle%252fHow-to-configure-IIS-for-relay-with-Office-365-eb57abd2-3859-4e79-b721-2ed1f0f579c9
Thanks for your reply Oleg,
I did more troubleshooting and I think my problem does relate to the fact the relay account is reaching its limit, say the number of messages being sent out in an hour. Since it was used by multiple MFDs, and at a certain situation when the account was sending a large number of messages, it failed.
I think the SMTP relay may be one option. Or just have to split the MFDs ups to use different Office 365 relay accounts.
Thanks,
Edmond.
