Serious SMTP Issue

    Since about two weeks I cannot use TNP on any of my new client websites any longer (Siteground Hosting). When I install the plugins external SMTP and enter clients Siteground Email SMTP credentials and then click on test, it goes into an endless spinning loop and then timeouts with 504 Gateway timeout.

    After that point my whole website becomes unstable and I need to deactivate TNP to continue working on the WordPress website. It slows down the whole server to the point of time-outs.

    This is a serious issue that occured on my last four client installs (always fresh WP install and always after configuring external SMTP in TNP).

    I contacted Siteground and they looked at it in their logs and made it clear this is a plugin issue.

    There seems to be a serious issue with your external SMTP plugin since one of your last updates. Please address this ASAP, as I cannot hand over websites to clients because of this TNP issue.

    BTW, I have the most recent version installed.

    Ok seems the issue can be resolved by switching to SMTP port 587 with STARTTLS. I will let you know if this continues to work, but for now it is looking good.

    I guess I cant use Port 465 any longer?

    hi, no changes have been made to the SMTP add-on about the protocols. The addon uses the library included in WP. Maybe another plugin is interfering but it is improbable. Try to use another SMTP plugin or ask the provider if something has changed.
