Issue with Mail send to GMAIL Accounts

[wieserkreativ]

Dear all,

maybe someone can help me - I have my domain registered at Shopify - but I am using a different mail client for sending mails - this is Hoststar. Since some weeks I have now issues with sending mails to gmail mail addresses - I always get an error message.

Therfore I tired to add several DNS lines into my domain settings at Shopify - but nothing helped really - maybe someone else is here, who had the same issue and found some solution - actually I added the following txt part:

Name: wieserkreativ.com

TXT Value: @ IN TXT v=spf1 a mx ~all

It would be really great if here someone could help me in solving that issue - as said - when I send mails to gmail addresses I always get back an error message - like the attached one:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

Thanks a million for your help. Maybe someone has an idea what the correct SPF entry in that case would be...
