Discussion:
sendmail from a jail - intermittent problems
(too old to reply)

I have a web server running in a jail that needs to send mail. The web
server script is configured properly and I get mail from it
intermittently... meaning, every once and a while but not reliably at all.
Here's the kicker: all the sendmail requests show up properly in
/var/log/maillog but most are just never received. They seem to vanish. I'm
confused how this could happen. I can reliably send mail from the command
line inside the jail.

Here is a recent snipped from the log entries trying to send mail from the
script. I've anonymized the email and domains to protect the innocent:

From what I can see the mail is going out fine but I never receive it. In
this case it's To: ***@gmail.com, who is a customer, and BCC: or
CC: ***@securesite.com which is my email.

Some details:
- FreeBSD 10.x with latest patches
- jail only runs Apache/PHP, sendmail, cron and syslog
- jail bound to lo1 as 10.0.0.1, no external interfaces
- Internal Sendmail running as a daemon
- no sendmail entry in the jail's /etc/rc.conf or /etc/rc.local
- mail is not being blocked by the firewall on the host
- host is running on DigitalOcean's public cloud. I don't know if they do
any outbound mail filtering to hosted customer services (doubtful)

Any thoughts on how to better diagnose this issue? Should I try to use an
external SMTP server? Ultimately I need to get the built-in Sendmail
working reliably however.

If I send mail to one of my own email addresses from the command line, I do
get the email. Here's what that log looks like. Maybe I'm missing something
obvious in the previous log.

Could be SPF or spam filtering type of issue? Take a look at the
headers on the mail you do receive. Did you try using telnet /
openssl s_client to send email from the jail?

An SMTP service might be a good idea, there are many which offer
free/gratis accounts for low/small volumes.

I double-checked and there's no SPF record for the domain. I should
probably add one to prevent spam in the future. :) Also double-checked that
the mail isn't getting filtered into spam on my recipient email - it's not.

Also I telnet into sendmail today from within the jail and was able to
successfully send mail & receive it on the other end. So I'm still at a
loss as to why most of the mail from the server is vanishing... and
finally, I took a look at the headers from the last good email received
from the server and there's nothing obvious to me. I'll go through them
again just in case.

From what I can see the mail is going out fine but I never receive it. In

- FreeBSD 10.x with latest patches
- jail only runs Apache/PHP, sendmail, cron and syslog
- jail bound to lo1 as 10.0.0.1, no external interfaces
- Internal Sendmail running as a daemon
- no sendmail entry in the jail's /etc/rc.conf or /etc/rc.local
- mail is not being blocked by the firewall on the host
- host is running on DigitalOcean's public cloud. I don't know if they do

Any thoughts on how to better diagnose this issue? Should I try to use an
external SMTP server? Ultimately I need to get the built-in Sendmail
working reliably however.
If I send mail to one of my own email addresses from the command line, I

Could be SPF or spam filtering type of issue? Take a look at the
headers on the mail you do receive. Did you try using telnet /
openssl s_client to send email from the jail?
An SMTP service might be a good idea, there are many which offer
free/gratis accounts for low/small volumes.
