We have verified that when message retrieval is enabled for a mailbox, autoresponder don't work.
The sender of the mail doesn't receive the mail with the text of the autoresponder.
Example:
I have a mailbox xxxx@gmail.com
I retrieve this mail address with SM in my mailbox xxxx@mydomain.com
I send a mail from yyyy@gmail.com to xxxx@gmail.com
I correctly receive the mail on xxxx@mydomain.com
If i set an autoresponder in SM, yyyy@gmail.com doesn't receive any mail.
Is this a SM issue ?
Thanks.
