[Mailman-Users] GMAIL

Sorry if this is a repeat I havent been able to find a definitive answer on this through Google so I just joined this list. Does Mailman have issues with GMAIL? I am hosting two lists and when I send an email to the list from GMAIL it makes it to the archives on the list's web interface but never mails out to everyone. Emails from hotmail or other accounts seem to work fine.
