Beware that this error might also occur when the from email does not match the username.

So, be sure to test the value myemail@domain.com is the same on user and from.

If it works when both fields have the same value and doesn't work when the from is different from the user, it means you should contact the company responsible for the email server and ask them to create a shared account and add SendAs priviledges for the account.

Answer provided by Luis Cruz is the right one.. However, I will try to be more descriptive though,

We were trying to send mail in Mantis Bug Tracker through Office 365 account and were facing the same issue. Below was the config,

$g_enable_email_notification = ON;
$g_phpMailer_method          = PHPMAILER_METHOD_SMTP;
$g_smtp_host                 = 'smtp.office365.com';
$g_smtp_username             = 'abc@acme.com';
$g_smtp_password             = '****';
$g_smtp_connection_mode      = 'tls';
$g_smtp_port                 = 587;

Clearly what we were missing was the 'from' property. Adding following properties resolved the issue,

$g_from_name               = 'Mantis Admin';
$g_from_email              = 'abc@acme.com';
$g_return_path_email       = 'abc@acme.com';

SMTP auth fails with '550 5.7.1 client does not have permissions to , SMTP auth fails with '550 5.7. 1 client does not have permissions to send as this sender' Open the Exchange Management Console. In the console tree, click Recipient Configuration. In the result pane, select a recipient. In the action pane, click Manage Send As Permission (or right-click Properties on the recipient). I have a user that send email using Outlook 2007 where he can choose from 2 account when sending email. His main Exchange (2010) account works fine. But when he tries to send as his other account (Also on Exchange) set up as an IMAP account he get this message: 550 5.7.1 Client does not have permissions to send as this sender


There can be many reason for this issue, One of this is which is most frequently comes because

Login name and From address is not same.

Login = 'abc@gmailcom' FROM = 'abc@gmailcom'

Now use these variables, It will work.
