Check mail sending ?

[Pierluigi Frullani]

Hello all,

  I'm playing with a powerscale 9.5.0.6 and I'm trying to setup some mail notifications.
Ive configured the email settings in general and the channel on event and alerts, but when I try to send a test event I get the ui that say "teset event sent successfully" but nothing goes out from the nodes.
It look like the sendmail ( or whatever it is ) is not running or hanged.
The /var/log/mailllog is empty and a tcpdump on all nodes shows no communications are happening.
What other can I check ?

Thanks in advance.

Pierluigi

I would check to see if there is a firewall or router dropping the packets or if your mail relay has an allow list for relaying mail.

Have you also tried telneting to your mail relay's IP/Port from the nodes?

Hello and thx for your time.

I have tried a telnet to mailserver, port 25 and works, and also tried to "send" a mail via telnet ( on port 25 ).

This is the transcript :

telnet mx.server 25 

Trying mx.server...
Connected to mx.server
Escape character is '^]'.
220 mx.server ESMTP
helo isi-1
250 mx.server

mail from: test@isi-1

250 ok 

rcpt to: ad...@mx.server

250 ok

data

354 go ahead
test-mail

.

250 ok 1709570878 qp 5927

quit

221 mx.server

and ad...@mx.server have received the mail.

It seems that on powerscale the sendmail ( or whatever is colled on ISILON ) is not running. 

On isilon 7.X  there where a bunch of service cee- something that where responsible of all log and mail send ( and snmp trap  for that matters ).

Now I cannot find a way to restart those services.

try sendmail -bt us...@wherever.com

Include output.

Also, not sure if they are even using sendmail or something else but find the /var/spool/mqueue dir or wherever sendmail is spooling to and see if the queue is stuck.

Maybe mailq will work, or maybe just ls in the spool dir.

There is no sendmail binary on OneFS 9.x ( at least not on 9.1+ ).

isi-1-1# find / -name sendmail\*    
/usr/lib/debug/usr/libexec/sendmail
/usr/share/sendmail

Hm.

We'd have to dig around and see what mailer they are using.

Email sending works as expected here, not much evidence in the emails how it sends them....

They are freeBSD based, so I presume "dragonfly" but I've got no experience with this. Seems like a rabbit hole.

Mail Transfer Agent (MTA)

The Mail Transfer Agent (MTA) is responsible for receiving incoming mail and delivering outgoing mail. Starting with FreeBSD version 14.0, the default MTA is DragonFly Mail Agent (dma(8)); in earlier versions, it is sendmail(8). Other MTAs, including Exim, Postfix, and qmail, may be installed to replace the default MTA.

I’m pretty sure that all mail sent from a powerscale cluster is using python libraries that are part of the “celog” alerting system.  I don’t recall it using FreeBSD native mail binaries to send mail. 

There’s some logging per node from celog for mail being sent along with a path in ifsvar that has alert attachments and history of sent alerts via smtp.

Yes, also I think it goes from a python, still need to find which service is responsible.

Thx
