[solved] Could not start mail function

Hi,

Do you see the emails in the Customers>Emails menu ?
If so, then HikaShop is sending the emails to the email server but the email server can't send them.
In that case, you should contact your hosting support or server administrator so that they can check the log of the email server where the error will be logged. That will allow you to know what's going on.
In HikaShop you have some email settings in the Main tab of the HikaShop configuration. You might need to adapt them based on the recommendation of your hosting.

Hi,

Well, there is no particular thing to change for SMTP in HikaShop.
However, since you're using another method to send the emails, it might have other requirements.
For example, if you include a PDF invoice in the emails, maybe the SMTP server doesn't like that.
Or maybe the enconding format of the emails needs to be changed. It's hard to say without looking at the error in the log of the email server. That's why contact the hosting support is what I recommend. You already know that HikaShop do send the emails to the email server, so it means that the email server doesn't send them for some reason and the reason will be in the log of the email server.
