SMTP settings for IIS 6.0 connecting to O365

[Mark Louie Diaz]

Hi,

May I ask your assistance how can we limit our IIS 6.0 SMTP server so that it won't be blocked by O365 when it reached the limit 30 email per minute or 10,000 emails per day. Hope it could que the email so that it wont be going into the bad mail folder.

Best Regards,

Hi @Mark Louie Diaz,

You can also put your public IP in whitelist on Anti-Spam on FOPE in Exchange Online, but you can have issues. If you are using to send Newsletters is advised to use a third party tool.

Here you have the article regarding the SMTP.
