When i’m sending email through SMTP credentials, I’m getting error that peer certificate does’nt match with domain name how to fix this issue please help me here

Have you install the certificate (lets encrypt i presume) to match what your using on the smtp settings.

Yes I install the SSL certificate for the domain, this only happens when I’m setting up “wp mail SMTP” for website

Other tool which I’m using SMTP workers fine I also tested with gmass SMTP it’s working fine but only this error log comes for WordPress

So the error, the first domain that you have red lined out is different to the second red lined out domain name. Is that error in the virtualmin mail log?

Both the domain same the first is and next red line cut is

I haven’t get any error in virtualmin log it’s perfectly working for all SMTP which I’m using only happens with using SMTP in WordPress
