[Dirk Estenfeld]

Hello,

 

we have received an error message from a customer that he gets when he
specifies several different gmail recipients in one email:

I assume this has to do with the fact that sendmail connects once to the MX
when the domain is the same and then transmits all mails to the same domain
and gmail seems to like that not (anymore?).

Is there any way to change the setting in sendmail or is a solution to
switch from sendmail to postfix?

 

Best regards,

Dirk
