Can't send emails (again)

[claire256]

First time trying to send an email since Friday.  It's displaying the following message and won't send the email:

Wrong or missing login data to access e-mail transport server 127.0.0.1. Please check associated account's settings/credentials.

It looks like I'm not the only one this is happening to and hoping it will be sorted out quicker than the last problem we had recently.

Hi claire256, the incident was fixed yesterday. Your mail should be working normally now.
