Hello,
I came to work this morning and this is what happened:
There is a goup : VSS_Kosice
Someone tried to send an email to this group, but noone received it. Than we took a look into his “sent” folder in his mail box and we saw that the group in the send to field looked like this: VSS_Kosice@VALEO
This is not the only group that causes this problem as we found out later. It was working just great a day before.
Do you have any idea what is causing this problem?
Well, this problem has appeared some time ago when we upgraded antivirus. It was working fine for about a month and than the warnings stoped to be sent to the users. I took a look into the logs and I saw that all mails were sent to the proper persons, but email adresses of the persons had “@VALEO” string attached to them and the result was that mail routing was not working. We solved the problem → stoped notifying all the users, only admins
Thank you very much for your help.
