| We are receiving the following message up to EIGHTEEN (18) per day:
Faulting application SMTPd32.exe, version 7.11.30.0, faulting module msvcr80.dll, version 8.0.50727.1433, fault address 0x00011eeb.
This is causing files to be orphaned in the spool folder (up to 2,500), and causing messages to be lost/not delivered to users.
Can anyone help?! We discovered this problem on Fri (2/15/08) afternoon, but the Ipswitch tech support is closed during the weekend and the U.S. holiday today (Monday 2/18/08).
We are running:
- version 9.23
- Premium Antivirus, powered by Symantec
- StarEngine Premium Filter (Anti-spam)
We have read some earlier posts, and made the following settings changes, but it has not helped so far:
- changed SMTP timeout in the registry to 20 seconds
- using only 2 black lists
- SMTP service set to restart after 1 minute in Windows Services
SMTP Settings:
- Tries before return to sender: 20
- Max tries for NULL senders: 1 (Delete after max tries is CHECKED)
- Max Invalid Recipients Per Session: 2
- Check Valid Sender is UNCHECKED
- Auto Deny Possible Hack Attempts is CHECKED
- Max Connections: 50
- Max Threads: 60

| well try only two blacklists... zen and spamcop...
btw 9.23 sucks... they have new beta files that do not crash. you might have to wait until the next release. i would call support. they will tell you to get rid of your blacklists... but then you will get lots of spam. kind of a crappy solution.
so try 2 lists. do not use any "block all ips from this country" blacklists. |

| Good news. Several changes, and I haven't had a crash of SMTPd32.exe in almost 20 hours.
I contacted support, and they gave me some new Dlls to install. We also removed the all the blacklists, since timeouts on the blacklists seemed to be correlated with the crashes.
Another problem we found was that our ISP had changed DNS servers without telling us. That meant that the mail server was having to use the secondary DNS instead of the primary DNS. This might have also caused longer lookup times that may/may not have caused the crashes.
Thanks to the Ipswitch tech support. They did a great job helping.

| gosh same here... tw telecom's server started failing pings 3 out of 4 attempts which would crash our server.
remeber to change it at the NIC level and at the smtp service level.
if you have an internal win2k3 dns server... you could tyr pointing to the local address as well. for one of our servers this helps alot. |

| | if dnsrbl's responds swift you should have no problem 03:06 23:59 SMTPD(7742029000002a91) [00001304] <smtp.soko.nl> BLACKLIST: retrying service (dynablock.njabl.org:*:dynablock.njabl.org)
This made my server stall.. messages like 421 Server to busy messages not arriving I heard from support that there is a 21 sec time out on DNS lookups (for dnsrbls) much to long imho.. |

| | Regarding SMTPd32.exe crashing: I have just spent the last four weeks of my life babysitting this issue  And I have discovered the following ... I discovered that enabling verify helo/ehlo, OR REVDNS, or Mailfrom all caused the SMTP to crash WHEN rules.ima included these x-imail-spam headers to forward email to the spambox or NUL. After trying one at a time, all at a time, it did not change the crash pattern. There are no known issues with the speed of DNS resolving. CONCLUSION:
I have enabled ALL connection filters without a problem after removing the x-imail-spam headers that included VALHELO, MAILFROM, or VALREVDNS from the rules.ima file. I am using the IMFILTER utility to propagate the rules to the top directories of each domain, and distribute the .fwd files to each user, making sure to not re-apply the rule for the spambox email address by removing the .fwd files from that user account. I set my delete after number of tries setting to 2. Therefore, I have no stats on what is being deleted other than to say any mail failing the VALHELO, MAILFROM, VALREVDNS, or is flagged by my six DNSBLs the email will be deleted.
