Postfix is not receiving external mail

zw flag

I have an issue with Postfix in which is not accepting external mail. I can send mail locally, but it get's stuck in queue. Post fix was working correctly until I attempted to send out a mailing list of 25k emails. The system crashed, I removed and re-installed Postfix and now I can't get it to work. I've tried putting it as "All" and it stops receiving mail internally/locally as well. I was wondering if anyone could assist me please. Thanks in advance. I see port 25 listening.

sudo netstat -plutn | grep 25 tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 24124/master tcp6 0 0 ::1:25 :::* LISTEN 24124/master

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
