Certain characters in recipient address can cause email to fail

Cacti is failing to send email (for reports, issues, etc) when there is a plus sign in the recipient email address, in my case, ubuntusv+orion@mydomain.com. If that's the only recipient defined, mail will not be sent out. If there are more than one recipients defined, mail is sent out but only to recipients without the plus sign in the email address.

Email addresses in settings_test_email in the settings table and email in the reports table are both saved with plus sign.

I can replicate this issue every time.

Please provide details from your mail server relative to the failure issues.

Never mind. Loving regex borrowed.

Resolved.

I have the same problem with a mail address containing dash (-) in domain name.

[cigamit]

Better now?

[gdsotirov]

Yes. Already tested it on my installation (I mean even before the PR).

[cigamit]

hehe, yup. All good on this side too. Thanks for the help.

I have a similar issue with the "Notify Primary Admin of Issues" funtion, the log show this:

09-02-2019 09:25:41 - MAILER WARNING: Mail failed from '"Cacti" probando@gmail.com', to '', cc '', Subject 'Cacti System Warning', Message: You must provide at least one recipient email address.

The selected user in authentication page has a valid email address and the test/thold emails works fine.

I'm using stable 1.2.1, is this issue solved in development branch?

[cigamit]

It is, though that format does not seem quite right. Update lib/functions.php and test away though. If this is a new install, you might just want to clone as there are several other changes that may introduce bugs if you do not pull the remainder of the files. Not too many file though.
