Problem sending email to office 365 users
Good morning
I have a VPS from where I send emails to my clients and suppliers and I am receiving an error to send to more than 2 recipients who have their emails with office 365, the error I receive is the following:
SMTP error from remote mail server after RCPT TO:@xxxxxxx.com>: 452 4.5.3 Too many recipients (AS780090) [BN8NAM11FT003.eop-nam11.prod.protection.outlook.com 2023-04-21T15:46: 05.104Z 08DB4184483426D3]
All emails are legitimate and are not spam.
