so, is this an issue/bug ? or just miss configuration ?

what do you think ?

i hope this is my mistake…
if not…then developer will have +1 homework

I think it’s something to do with some mail systems want actual sending mail server mach.

some past version (i forgot what month)
it’s working…
i can use mail.client-domain.tld
but few days ago it came to failure

I just checked I use same plugin free version on one site with own maiserver, that’s working fine even use not main mail server host

so… at your side, it’s working :frowning:
i tried free version too, same result… error :frowning:
omg… is this my local problems ?

When you send test mail what full error report say?




look like everythings is okay
but…
