XF 2.2 I am having email issues.


New member
I am running XF2.2 on php 8.2 on windows server.
SMTP is set up and working on mail.xxx.com Port 25

I can request a password reset no problem, the email is sent out and no errors in the server error log.

This indicates to me that the smtp mail server is fine.

However when I reply to a message I see the following in the error log.

  • Swift_TransportException: Email to xxxxxx@outlook.com from x@xxxxxxx failed: Unable to send mail.
  • src\XF\Mail\Mailer.php:315

Stack trace​

#0 src\XF\Mail\Queue.php(148): XF\Mail\Mailer->send(Object(Swift_Message), Object(XF\Mail\SmtpTransport), Array)

I have not configured anything in XF as I assumed php will take care of it.

Most likely your IP address is being blocked by the email providers - Microsoft are particularly strict about this type of thing.

It's almost impossible to rely on PHP to send email directly these days - it may work for a while, but eventually you'll get blocked, especially once you get any kind of volume happening.

My advice is always to use a 3rd party Email Service Provider, such as Amazon SES, Mailgun, Sendgrid, Postmark, SparkPost, etc

Either way, you should definitely be setting up SPF and DKIM - these are pretty much mandatory for getting mail delivered reliably these days.
