PHPmailer function stopped working...

[#1]

Hi, I use the phpMailer function to send mail from my website (on Hostopia), and have been for a long time.

Randomly this morning, I discovered nothing was being sent - with this error coming back 'Could not instantiate mail function.'

I haven't made any changes to code in quite a while (and it was working fine on Friday) - any ideas why suddenly not working?

I use the basic phpMailer - not with smtp, and has worked fine up till now ...

Thanks

Andy

** quick update

Have also tried my other two websites, which run under wordpress (so use other methods of mail processing) also failing to send messages ..

I'm getting the same error from PHPMailer version 5.2.16 using its PHP Mail() interface

Message could not be sent. Mailer Error: Could not instantiate mail function.

If I use PHPMailer with SMTP the message is apparently sent to localhost, but potentially isn't accepted by the mail server; it doesn't get delivered to Plusnet or gmail.

SERVER -> CLIENT: 250 2.0.0 u7UApc4I012916 Message accepted for delivery
CLIENT -> SERVER: QUIT
SERVER -> CLIENT: 221 2.0.0 web218c50.megawebservers.eu closing connection
Connection: closed
Message sent: date Tue, 30 Aug 2016 11:51:38 BST

Edit: Trying to use the sendmail interface also gives an error

Message could not be sent. Mailer Error: Could not execute: /usr/sbin/sendmail -t -i

Raised with Hostopia (ref: 3933885). Thanks for bringing it to our attention.

Thanks Bob, seems to be back up and running now.

Thanks, Hostopia confirmed late yesterday that they'd fixed the problem. Everybody happy there are no residual issues?

Edit: Hmmm, I seem to be getting two copies of each email when I'm testing?

Yes, sending using PHP mail() directly and via PHPMailer works OK now. Sending with PHPMailer also works using sendmail and with SMTP to localhost.

This applies for messages sent to both Plusnet and gmail addresses.

Edit: And I get only the expected copies.
