Gmail is rejecting SmarterMail password reset emails because of null sender on From line

Hi SmarterTools team! I had a customer report to me that SmarterMail password reset emails were getting rejected by Gmail with the following message in the Delivery log...

[2019.07.31] 12:58:03.097 [07750] RSP: 550-5.7.1 [xxx.xxx.xxx.xxx      14] Messages missing a valid address in From:
[2019.07.31] 12:58:03.097 [07750] RSP: 550 5.7.1 header, or having no From: header, are not accepted. r22si82549113ioh.94 – gsmtp

When I looked at the From address it is as follows...

[2019.07.31] 12:58:02.816 [07750] CMD: MAIL FROM:<> SIZE=1803

This tells me that Gmail is rejecting the message because system messages are sent with the null sender <>.

I'm proposing that SmarterTools change the null sender on system messages to an actual email address so that Gmail stops rejecting these. 

Thanks for your consideration.

Linda, this was corrected in the latest releases of SmarterMail. Once updated, navigate to Settings>System Messages to configure the from name and address information with something valid, and you should start seeing these messages delivered successfully.
