Sendmail stops sending outbound e-mail

[RyHD]

We have been having an issue with Scalix where on a daily basis (usually by the time i come in in the morning), e-mails are not being sent to the outside world. I have gone through the fatal log and couldn't seem to find any indication as to why. Restarting Scalix Services would not resolve the issue, so we started rebooting the server each time this behaviour occured. Eventually, i found that the only thing we needed to do was run [b]/etc/init.d/sendmail restart[/b] and mail would begin to flow again. Where can I look to see why sendmail is having this issue, and has anyone experienced this before?


Thanks,
RyHD

Sendmail logs information to /var/log/maillog on Red Hat installs and /var/log/mail on SUSE installs.

Thank you for the quick response! The /var/log/mail file is loaded down with these errors:

stat=Deferred: Connection timed out with ryans.com.
daemon=Daemon0, relay=localhost [127.0.0.1]

The Scalix Services are all running when it is getting these erorrs. Where else could I look for more info, or is there something i could try?

Thanks,
RyHD

The first thing you need to do is to work out why connections are timing out when talking to that particular host. Until that's fixed, you'll still get the errors.

If there's nothing listed in the queues when you run omstat -s and restarting sendmail fixes the problem, it's a sendmail issue.

You can manually force processing of the queue by running the command

Code: Select all

sendmail -q

.

Cheers

omstat -s shows no messages in the queue after the sendmail restart, however, the sendmail /var/spool/mqueue folder is loaded down with items. I understand this is likely to be a sendmail issue, but was wondering if it is possible to uninstall Scalix Server (saving message store), uninstall Sendmail, reinstall Sendmail, reinstall Scalix Server, and not blow anything up? I just cant seem to get this one figured out, and am hoping it's just a botched sendmail. Also, these problems started after the following had been done:

We had the ARCHIVE=bcc:address@domain.com option set in the general.cfg, but when the account wasn't checked after a couple of days, when it tried to pull down the e-mail into the mail client we had been using for that account, it would fail to delete any of the mails off the server, and would cause the server to stop processing e-mail. We went back and removed the ARCHIVE=bcc:address@domain.com, and since then, have had to reinstall the Scalix Server because of services dying sporadically. Is it feasable that the ARCHIVE option might have hosed sendmail?

Thanks Again for the quick reply,
RyHD

Hi. I don't think it's a botched sendmail installation, but perhaps something in the sendmail.cf, access, mailertable, etc files isn't correct. Could you post your sendmail.cf file to start with? Also, run "mailq" on your server and take a look at some of the messages that are queued up. Are they all destined for the same server? How long have most of them been in there?

Going back to the original problem with sendmail stopping, can you run:

Code: Select all

ps -aef|grep sendmail

the next time you notice mail not going out?

Thanks,
Rachel

I should be able to get you the ps grep request tommorow, as it seems to be down every morning i come in.
here is the full text from sendmail.cf. I am hoping this is the correct one, as i have the following files in my /etc/ directory:

Hello,

please enable DEBUG_LOG=TRUE in /var/opt/scalix/sys/smtpd.cfg. Shut down smtpd using omoff -d0 smtpd and omon smtpd to turn it back on.

Be aware of a 2GB logfile limitation, so if you get a LOT of mail, check this file frequently or bad things will happen(tm). Let this logging go on until this situation comes up again, then paste anything here that {NULL}.

Thanks,

Sascha.

Where is the debug log stored, so that i might prevent Bad Things (tm)?


Thanks,
RyHD

I have generated the smtpd.log file and need to know what you want me to paste here in the forum?

I don't understand.

Hi. Is your domain ryans.com or is that another domain you send to quite often? If it's the former, it looks like you don't have ryans.com in your /etc/mail/local-host-names file. Add that to the bottom of the file, then restart sendmail.

As far as the smtpd.log file goes, hold on to that for right now and let's see what happens when you come in tomorrow. If it's the /etc/mail/local-host-names problem, the problem may have been that you're looping mail over and over until you run out of connections.

Thanks,
Rachel

Added the ryans.com entry to /etc/mail/local-host-names but the problem still persists. IT seems other issues seem to be occuring as well. At first I thought it might have been isolated, bt this seems to be happening more and more often now. IF a user has alot of e-mail in their inbox, the pop3 interface will stop responding and not delete e-mails off the server.
