Stopped working: does not send emails

    Hi!

    I used this plugin (that I like because it’s straightforward!) for many months and now it stopped working. When I try to send a test email, the page is just reloaded, but there is no log or error message. When people try to request a forgotten password, they get the error message that the email cannot be sent.

    I changed my website from simple WP to multisite recently – could this be a reason?

    My configuration:

    OS: Linux sonny.shared.1984.is 4.19.0-8-amd64 #1 SMP Debian 4.19.98-1+deb10u1 (2020-04-27) x86_64
PHP version: 7.4.21
WordPress version: 5.8.1
WordPress multisite: Yes
openssl: Available
allow_url_fopen: Enabled
stream_socket_client: Available
fsockopen: Available

    Ok, now this is funny. First of all, there seems to be a link with the multisite. On the first site, SMTP Mailer does not even manage to try to send a test email. There is no output. On the second site, I do get output. But interestingly, SMTP Mailer seems to try to send email using the address associated to my WP user, not the address that I entered into the fields:

    2021-10-06 08:50:00 SMTP INBOUND: "235 2.7.0 Authentication successful"
2021-10-06 08:50:00 SERVER -> CLIENT: 235 2.7.0 Authentication successful
2021-10-06 08:50:00 CLIENT -> SERVER: MAIL FROM:<[email protected]>
2021-10-06 08:50:01 CLIENT -> SERVER: DATA
2021-10-06 08:50:01 SMTP INBOUND: "554 5.7.1 <DATA>: Data command rejected: Could not find envelope sender user [email protected]"
2021-10-06 08:50:01 SERVER -> CLIENT: 554 5.7.1 <DATA>: Data command rejected: Could not find envelope sender user [email protected]
2021-10-06 08:50:01 SMTP ERROR: DATA command failed: 554 5.7.1 <DATA>: Data command rejected: Could not find envelope sender user [email protected]
SMTP Error: data not accepted.

    [email protected] is the email address of my WP user… not the address that SMTP Mailer uses to successfully log in to the mail server…

    @veganist, Do you have any other email plugin? The plugin utilizes the built-in wp_mail function that comes with WordPress. The wp_mail function can be customized with action hooks and filters.

    You can temporarily deactivate one plugin at a time to see if there is a conflict.
