Server 5.2 missing SMTP Logs

OK, thanks so much. I'm pretty much a newbie when it comes to this type of stuff. But I believe I followed your instructions correctly and (tho I'd never done it before), read-up on how to create a cron tab which, when I check using crontab -l, now says 10 * * * * /usr/local/scripts/mail_log.sh which is what I named the file containing your script.

It's been well over 10 minutes now, since I set up the cron tab, but I'm just not sure where in the Server app I'm supposed to start seeing the mail log? In the "Mail" section of the Logs popdown? I see Mail Server Log, but that only shows various people logging in & out of their mail apps, and runs back several days. Do I need to restart the Mail service (or the server itself) to kick this off?

It won't work as just a 10 isn't dividing the hour in 6. Use the cron tab below (it also puts the errors in the crontab.log).

*/10 * * * * /usr/local/scripts/mail_log.sh >> /var/log/crontabs.log 2>&1

The SMTP log should re-appear in the Server.app in the logs pulldown menu.

I must be doing something wrong... Still no SMTP log appearing in Server.app. And for what it's worth, mail.log in /var/log still shows Zero bytes, and no crontabs.log has been generated there, either.

Did you sudo for the cron tab?

sudo env EDITOR=nano crontab -e

Bingo! No, I hadn't done sudo, sorry.. that cron tab tutorial I found didn't mention it. Now that I did, it's all working. Thanks again for your help!

You're welcome. Be sure to remove it from you user cron tab now.

Thank for that, certainly helpful.

Unfortunately, I still haven't got the entire log control that I had before.

I have some emails that are confirmed received by the SMTP server but never delivered (but that's only a guess) to Dovecot as they don't appear in the Inbox.

Unfortunately I am unable to confirm wether this email has or hasn't been delivered. Some fault are being displayed in the logs but not sure if all are and certainly successful deliveries aren't showing in the SMTP logs.

Any idea please? Rather frustrating

server:~ admin$ sudo serveradmin settings mail:postfix:log_level

mail:postfix:log_level = "debug"

Hi, after following some of the suggestions made earlier in this thread, like you I saw that the level of info of the SMTP log that I was able to produce and view through the Server.app was not as detailed as I needed and remembered from earlier Server versions. Luckily, I was able to adapt another suggestion and figured out how to save more detailed log info to a textfile.

Upon boot-up, I issue the following command in Terminal:

log stream --predicate '(process == "smtpd") || (process == "smtp")' --debug > /Users/admin/Desktop/"$(date +%Y%m%d-%H%M%S).txt"

Then I minimize the Terminal window to the dock. The command creates a dated textfile on my desktop that stores a running mail log, fully detailed with "sent" indications, IP addresses, etc., like I used to get in the mail log using Server.app. Yes, it's not ideal since I have to keep the Terminal running in order to capture this info, but our server doesn't have anyone working at it regularly, so the Terminal can run undisturbed in the dock. When I want to end one of these textfiles and begin another, all I have to do is quit Terminal, store the generated textfile somewhere convenient, and then re-issue the above command to begin a fresh textfile "log". Obviously on your server, you would change the username in the command to your own, and change the saved path as well, if desired.

Tks for that.

Just tried that and the txt file is created however I am not getting anything written in it (zero bytes).

Anything that you can think of?

Tks again for that, really appreciate ;o)

For me, at least, the text file is empty only at first... but once mail begins to move through the server, it begins to fill with info. I usually keep the file minimised in the dock, but each time I display it I see that more entries have been added.
