Support » Plugin: WP Mail SMTP by WPForms » “Other SMTP” security?

  • Resolved aggk



    I was reading your docs on defining password in wp-config.php for “Other SMTP”.
    It does seem like a really good idea.
    I guess it would make security equal to WordPress own way of storing database access?

    Are there any big security concerns that would motivate setting up an account at Mailgun, Sendgrid or Gmail?
    I believe the big benefit of using our existing SMTP -account is we would not need to pay 79$/month for a dedicated sending ip? (we will be using WP Mail for transaction and contact form, app. 400 e-mail sent/month in total)

    Grateful for your comments on this, thanks!

    Yes, storing things in wp-config.php is absolutely the same WordPress stores its DB access and tokens for cookies generation.

    Regarding other mailers:
    1) you can store settings for all mailers in wp-config as well (all those API keys, Client ID/Secret etc). There a bunch of constants available in Options.php file (looks for is_const_defined() method).
    2) with your 400 emails per month – any of these solutions: Gmail/SendGrid/Mailgun – will be absolutely free for you (they all have a free plan). So you can pick any. I would personally take the Mailgun, I think (not aff, personal preference).

    Thank you Slava!

    But are there any big security concerns that would motivate using Mailgun/SendGrid/Gmail over “Other SMTP”?

    Yes, Mailgun/Sendgrid etc have generous free mailing limits, but only when on shared ip:s

    The way I see it, using our existing “Other SMTP” would be the best alternative.
    But to be honest it´s a little intimidating printing the password, is it a safe/recommended way? (we are on WP Engine that I belive has great security in place)
