my email settings on magento and email server is fine and they are working. I have an email forwarder for my magento shop. my current version is 126.96.36.199 . we ar enot looking to ugrade it for technical reasons. Magento works just fine for us when our customers place na order.
However, ocassionaly we run into problems where things get overwhelming. yesterday one of my customer did you receive the email confirmation email after he placed an order. and then there's 2 more customers today said they did not get the email confirmation email after they've placed an order in my website. we have not made any changes in the email that goes out. The only change we did today was changed the host and port from the exisitng settings to "host" and "port" given by our provider Nexcess. However, I do not think making those changes in magento email settings caused any issue that made these 2 customers not get the confirmation email today. because, even before I made the changes yesterday I still got acustomer who did not receive the email confirmation. we have a pretty big customer base. and this is beccoming stressful to handle. any suggestions or ideas on why this happens?
