    Hi there,

    I sometimes receive the following error from my smtp server: Too many concurrent SMTP connections; please try again later.

    But the email is not resent by PostSMTP after failing and getting the error: Too many concurrent SMTP connections; please try again later.

    Is it possible to PostSMTP to resend the email automatically after x amount of time until the email goes through

    Thanks for you help.

  • Hi @service9000,

    This is not currently supported. The only option I could suggest would be considering a fallback SMTP service that can be used in the event of a problem such as this.

    You could also talk to your hosting provider (if you haven’t already) about why this issue occurs. If you are sending a huge volume of mail, then you should consider something like SendGrid/MailGun/Amazon SES, etc.

    Hope this helps.

    Kind Regards,

    We are not sending a huge volume, only around a hundred in a day, that should not be an issue, we only send once at a time with the Post SMTP plugin, we already talked to our provider but they are not cooperative and are telling us we are connecting more than once from the same ip, which is not true when I look at the logs.

    Is there any way to change the delay before it tries the fallback server after failing on the main server? if so, I could make it retry on the same server via the fallback settings after x amount of seconds.. thats an idea

    Also is there a way to have more detailed SMTP logs with the exact error number returned by the server maybe?

    Do you have any other suggestion apart from paying an other provider like mailgun to handle 100 emails per day? seems like a big overkill solution to our issue..

    Thank you for your help! Really appreciated!

    Hi @service9000,

    I don’t think there is a way to change the number of seconds to check before using the fallback SMTP. If your provider is not very cooperative – I would personally use the other provider as your main SMTP sender! It’s not worth the risk.

    Also is there a way to have more detailed SMTP logs with the exact error number returned by the server maybe?

    I’m not one of the developers – AFAIK this is not supported at the moment.

    I have used Mailgun a few years ago and it did work very well – they do have a free plan for up to 5,000 emails a month, which might be a fit for your use case?

    I have also used Amazon SES which is one of the best services, but does indeed have a small additional cost associated with it.

    Hope this helps.
