UTM 9.351-3 SMTP proxy stops delivering, exim-out not running

EWIT

Our Sophos UTM 220 is running SMTP anti-spam proxy, and has been running well for many months. After the recent firmware update to 9.351-3 the SMTP proxy frequently stops delivering mail.

Messages are logged as moving to the work queue, but exim-out never actually picks up the messages and spools them for delivery. To clear the stuck mail I have to stop SMTPD, clear the retry timeout database, and restart SMTPD.

We are only using this for inbound filtering, and it's delivering to our in-house SMTP server, nothing very complicated.

exim-out ends with a simple message:

2015:11:23-10:31:15 firewall exim-out[29473]: 2015-11-23 10:31:15 End queue run: pid=29473

But the "start queue run" message doesn't reappear until after I restart the SMTP service. Obviously I can't babysit this thing all day. Any ideas?

    hello EWIT,

    i had the same problem a few days ago too. also firmware 9.351-3 but on a sg310. the exim-out stopped suddenly delivering mails without a failure message. the emails were collected somewhere, i could see it counting but i couldnt see them in the smtp spool. restarting the smtp service didn't help. there was no failure message. my service partner also had no idea what had happened. caus i had some pressure from time, i completely restarted the utm and all mails were delivered correctly. since then, it didn't happen again *fingers crossed*. i've never had this problem before. so this may be a bug in version 9.35.1-3.

    have you tried a complete restart? maybe this will help you too.

    greetings,
    Sebastian
