XF 2.1 Server error log: Unable to send mail. src/XF/Mail/Mailer.php:295

[Danny Fyne]

I'm using my own mail server and have no problem sending emails when it comes to registrations etc. However, when I try to do a mass mailing, apart from the test email which sends OK, when I send the mailing, it says the emails were sent OK but when I check the Server Error Log, all the emails have not been sent with the following error:

• Swift_TransportException: Email to xxx@xxxxxx.com failed: Unable to send mail.

This happens whether I use my own smtp server or the default in XenForo and both in plain text or html format. As I said, the test email works fine and all other email functions are OK when tested. It is only when mass mailing.

Any ideas?

Just to add... Since I tried to run themes mailing, the email system has stopped working and all emails sent by the system are showing the same error in log and nothing sent.

I'm using my own mail server

What do you mail server logs show?

My bad... I exceeded the sending quota for my mail server.
