[Mailman-Users] Do I need an MX Record

[Sullivan, John]

Hi all - I am having some problems sending out emails to my lists. 

 

I have Red Hat 8.0 

Sendmail 

MailMan 2.0.1 

 

I have a test lists set up with test users. 

 

When a user subscribes to the list they get a confirmation from the mailman
server but when they reply there email seems to just get lost. 

When I send out an email to the list nothing gets delivered. 

My server name is lists.mlsnet.com and my list is called 90minutes and I
should be able to send mail to 90minutes at lists.mlsnet.com
<mailto:90minutes at lists.mlsnet.com>  to send an email to all of the
subscribers. 

 

Here is some log errors from maillog file:

Do I need to have MX Records setup on my external DNS for this server?
