Hi @esmabama

Thanks for reaching out and we’re sorry to hear that you are experiencing issues with the Other SMTP mailer.

Could not connect to SMTP host

Based on the error message you received, the issue is server-related.

The ideal next step is to contact your SMTP/hosting provider with that error report to fix the server configuration or to see if anything is blocking it. They’d hopefully be able to help!

I’m sorry, but we can’t directly assist with this issue on our side since it’s SMTP/hosting-related.

Also please note, that the Other SMTP mailer option does not use a dedicated API, which can lead to potential errors based on your website hosting settings. In cases where ongoing issues arise while using the Other SMTP mailer, we generally recommend switching to a transactional mailer option (it’s all mailers except the Other SMTP and Default (none) option).

As a test or full-on alternative, you can try setting up one of our other available mailers by following the instructions outlined in our documentation.

I hope this helps!

Dear Drake,

I appreciate your reply. I have been in touch with the SMTP/ hosting provider for a while.

We did a test script to verify id the SMTP Auth was working:

# Get the credential

$credential = Get-Credential

## Define the Send-MailMessage parameters

$mailParams = @{

    SmtpServer                 = ‘smtp.office365.com’

    Port                       = ‘587’ # or ’25’ if not using TLS

    UseSSL                     = $true ## or not if using non-TLS

    Credential                 = $credential

    From                       = ‘affectedaccount@domain.com’

    To                         = ‘affectedaccount@domain.com’, ‘ExternalRecipientInCC@domain.com’

    Subject                    = “SMTP Client Submission – $(Get-Date -Format g)”

    Body                       = ‘This is a test email using SMTP Client Submission’

    DeliveryNotificationOption = ‘OnFailure’, ‘OnSuccess’

}

## Send the message

Send-MailMessage @mailParams

All emails were sent with no issue. So we conclude the problem is on the plugin side.

We are a NGO, with no budget for the PRO version, in order to use the mailer “365/ Outlook” (it is Microsoft providing our email server), we have been using “Other SMTP”.

Do have a suggestion on how to solve this situation?

Thank you for your time in advance.

Hi @esmabama

Thank you for getting back to us.

At this stage, we can only assume that there may be a conflict or firewall preventing the connection from being established via your website.

As a test you can try disabling your other plugins and switching to a default theme. It may also help to try using the same connection with different SMTP plugins to see if this really is a server-side/plugin specific issue.

We would also like to point out that you are able to use other mailers even if your email provider is Outlook/hotmail etc. WP Mail SMTP determines the From Email, but it doesn’t restrict it to a particular email provider or even a live mailbox if using a transactional mailer like Sendinblue for example.

I hope this helps.
