Question
Can send but not receive email, just using basic console mail like sendmail and mutt
- Posted April 15, 2014
I have: MX 1 mail.tanglewoodforest.tk. mail.tanglewoodforest.tk. IN A 192.241.200.53 @ IN A 192.241.200.53 @ TXT “v=spf1 ip4:192.241.200.53 -all”
- CNAME @
But when mail comes to me I see possibly resets in my tcpdump: 10:28:12.001021 IP mail-yh0-f43.google.com.48272 > tanglewoodforest.tk.smtp: Flags [S], seq 3986132201, win 42900, options [mss 1430,sackOK,TS val 4050176638 ecr 0,nop,wscale 6], length 0 10:28:12.001079 IP tanglewoodforest.tk.smtp > mail-yh0-f43.google.com.48272: Flags [R.], seq 0, ack 3986132202, win 0, length 0 10:30:09.455246 IP mail-yh0-f49.google.com.51782 > tanglewoodforest.tk.smtp: Flags [S], seq 2481880713, win 42900, options [mss 1430,sackOK,TS val 2250336 ecr 0,nop,wscale 6], length 0 10:30:09.455290 IP tanglewoodforest.tk.smtp > mail-yh0-f49.google.com.51782: Flags [R.], seq 0, ack 2481880714, win 0, length 0
I used to have no problem with this, but since I made a new droplet, I’ve never got it working again. I can send out from the droplet using Mutt just fine.

+=---------=+ <br>| Fixed It! | <br>+=---------=+ <br> <br>It’s all in “/etc/mail/sendmail.mc” <br> <br>Sendmail is setup to only accept mail from localhost. <br> <br>Changing: DAEMON_OPTIONS(
Family=inet, Name=MTA-v4, Addr=127.0.0.1, Port=smtp')dnl <br>To: DAEMON_OPTIONS(Family=inet, Name=MTA-v4, Port=smtp’)dnl <br> <br>The “Addr=127.0.0.1” parameter means to only accept email from localhost. <br> <br>But what I hadn’t done was the instructions at the top of the sendmail.mc file which is to recomile/remake the sendmail.cf file with: <br>make -C /etc/mail <br> <br>And now it works!Now i’m just trying to figure out how to get my original /etc/mail/* config files back to stock, since apt-get purge/autoremove/autoclean and then reinstalling didn’t help.
Host files good, DNS good, pointer good. Though when i run a sendmailconfig i do get these errors: <br>Creating /etc/mail/submit.cf… <br>Informational: confCR_FILE file empty: /etc/mail/relay-domains <br>Informational: confCT_FILE file empty: /etc/mail/trusted-users <br>Updating /etc/mail/access… <br>makemap: error opening type hash map /etc/mail/access.new.db: Permission denied <br>Reload the running sendmail now with the new configuration?

I’m not able to connect to port 25 on your droplet – is your mailserver running? Make sure it’s listening on the public interface. You can check what interface it’s listening on by running <pre>sudo netstat -plutn</pre>Also make sure that your firewall isn’t blocking connections to port 25. <br> <br>Finally, try removing the wildcard CNAME record and adding rules manually as needed as it might be conflicting with the mail record.
