Hello!
Happy New Year, everyone! I ask for help on this issue: I installed the Egeya blog engine for DigitalOcean according to the instructions from this blog “ How to get Egeya on DigitalOcean ”, but I encountered such a problem that the engine does not send letters when publishing comments from users on the blog, then I remembered that such a simple thing as sendmail can be responsible for the transport of letters, installed it, but did not configure anything. I left a test comment and received a letter in my Google Apps box, but when I decided to reply to this comment, I could not send anything to Mail.ru sendmail. I looked in the mail.log file on the path /var/log , and there I saw the following:
Dec 30 22:55:03 egeya-ubuntu-512mb-ams3 sendmail[29559]: gethostbyaddr(188.166.17.115) failed: 1 Dec 30 22:55:03 egeya-ubuntu-512mb-ams3 sendmail[29559]: gethostbyaddr(10.18.0.5) failed: 1 Dec 30 22:55:03 egeya-ubuntu-512mb-ams3 sendmail[29559]: alias database /etc/mail/aliases rebuilt by root Dec 30 22:55:03 egeya-ubuntu-512mb-ams3 sendmail[29559]: /etc/mail/aliases: 0 aliases, longest 0 bytes, 0 bytes total Dec 30 22:55:03 egeya-ubuntu-512mb-ams3 sm-mta[29666]: gethostbyaddr(188.166.17.115) failed: 1 Dec 30 22:55:03 egeya-ubuntu-512mb-ams3 sm-mta[29666]: gethostbyaddr(10.18.0.5) failed: 1 Dec 30 22:55:03 egeya-ubuntu-512mb-ams3 sm-mta[29668]: starting daemon (8.15.2): SMTP+queueing@00:10:00 Dec 30 22:58:33 egeya-ubuntu-512mb-ams3 sendmail[29831]: uBUMwWfQ029831: from=www-data, size=709, class=0, nrcpts=1, msgid=<201612302258.uBUMwWfQ029831@egeya-u$ Dec 30 22:58:33 egeya-ubuntu-512mb-ams3 sm-mta[29832]: uBUMwX0E029832: from=<www-data@egeya-ubuntu-512mb-ams3.localdomain>, size=972, class=0, nrcpts=1, msgid=$ Dec 30 22:58:33 egeya-ubuntu-512mb-ams3 sendmail[29831]: uBUMwWfQ029831: to=sergey@pisma.ws, ctladdr=www-data (33/33), delay=00:00:01, xdelay=00:00:00, mailer=$ Dec 30 22:58:33 egeya-ubuntu-512mb-ams3 sm-mta[29834]: STARTTLS=client, relay=aspmx.l.google.com., version=TLSv1.2, verify=FAIL, cipher=ECDHE-RSA-AES128-GCM-SH$ Dec 30 22:58:33 egeya-ubuntu-512mb-ams3 sm-mta[29834]: uBUMwX0E029832: to=<sergey@pisma.ws>, ctladdr=<www-data@egeya-ubuntu-512mb-ams3.localdomain> (33/33), de$ Dec 30 23:05:28 egeya-ubuntu-512mb-ams3 sendmail[29867]: uBUN5Sp4029867: from=www-data, size=468, class=0, nrcpts=1, msgid=<201612302305.uBUN5Sp4029867@egeya-u$ Dec 30 23:05:28 egeya-ubuntu-512mb-ams3 sm-mta[29868]: uBUN5S9T029868: from=<www-data@egeya-ubuntu-512mb-ams3.localdomain>, size=731, class=0, nrcpts=1, msgid=$ Dec 30 23:05:28 egeya-ubuntu-512mb-ams3 sendmail[29867]: uBUN5Sp4029867: to=zapara@mail.ua, ctladdr=www-data (33/33), delay=00:00:00, xdelay=00:00:00, mailer=r$ Dec 30 23:05:28 egeya-ubuntu-512mb-ams3 sm-mta[29870]: STARTTLS=client, relay=mxs.mail.ru., version=TLSv1.2, verify=FAIL, cipher=AES256-GCM-SHA384, bits=256/256 Dec 30 23:05:29 egeya-ubuntu-512mb-ams3 sm-mta[29870]: uBUN5S9T029868: to=<zapara@mail.ua>, ctladdr=<www-data@egeya-ubuntu-512mb-ams3.localdomain> (33/33), del$ Dec 30 23:05:29 egeya-ubuntu-512mb-ams3 sm-mta[29870]: uBUN5S9T029868: uBUN5T9T029870: DSN: Service unavailable Dec 30 23:05:30 egeya-ubuntu-512mb-ams3 sm-mta[29870]: uBUN5T9T029870: to=<www-data@egeya-ubuntu-512mb-ams3.localdomain>, delay=00:00:01, xdelay=00:00:01, mail$ Dec 30 23:17:19 egeya-ubuntu-512mb-ams3 sm-mta[1627]: gethostbyaddr(188.166.17.115) failed: 1 Dec 30 23:17:19 egeya-ubuntu-512mb-ams3 sm-mta[1627]: gethostbyaddr(10.18.0.5) failed: 1 Dec 30 23:17:19 egeya-ubuntu-512mb-ams3 sm-mta[1634]: starting daemon (8.15.2): SMTP+queueing@00:10:00 As I understand, the letter passed to the pisma.ws domain, but on the Mail.ru side, the letter did not pass the verification and was rejected by their server.
I have little knowledge in these matters, so maybe someone from the experts in this field will be able to advise me some solution for my problem, or maybe in the domain settings for my blog you can add some DNS records so that the letters do not got into spam and were not rejected by mail servers.
