Since upgrading to EE v2, we have been having problems with sending emails via the communicate module which had otherwise been working fine before.
As EE admin, I am receiving the sent emails, however several people within our domain are not receiving them. I have inspected the list of email addresses in the distribution list for any malformed email addresses, but have seen none.
We are running EE version 2.13 (build 20101220 ).
Any help would be appreciated.
