hi

our customer domain.com configured test@domain.com in outlook via activesync (using sogo)

he sent an email to test2@domain.com ie within the same domain, but test2@domain.com does not exist

instead of the email being sent and again bounced with an user does not exist message, mail stays in the outbox.

there is no non-delivery receipt either

i checked the forum and found this link
https://forum.iredmail.org/topic15598-b … eject.html

is there any solution for this ?

it is very important

thanks
rajesh

PS : please note that the same email configuration when done via standard smtp / pop / imap works perfectly
