Re: hMailServer has run out of memory

With about 100 users with HEAVY use (many large file attachments), I consistently get ~150-200MB mem usage. With ONE Apple Mail / Avast user It would quickly ramp up over 1GB and start causes issues. These users were on IMAP.

Re: hMailServer has run out of memory

If your Mac Apple Mail clients have avast anti-virus, it cause MAJOR issues with memory consumption. Hmailserver will run out of memory, and lost emails, etc. Now this was back in January 2016 that I discovered this. Maybe an Avast update has solved this I don't know. I have verified 100% that Avast...

Re: Help: How to reduce "out of memory errors" - IMAP users

I've done a bit more testing: AVAST does cause issues with some Mac users - emails missing. But no out of memory errors. I have tested Avira and AVG anti-virus and I did not notice any issues. So ALL of our mac users are required to uninstall AVAST and use Avira or AVG as an alternate. NO out of mem...

Re: Help: How to reduce "out of memory errors" - IMAP users

Mi Martin,

Do you have an alternate email address? Tried emailing, but bouncing back.

Typical mem usage now is ~130-200 MB. Great :D

I will be testing an alternative - AVG? Will get back.

Re: Word Search

The word searched for in the email MUST have a space on either side of the word, or it will not trigger a find. So if my blocked word is "shit" and email comes in with " This is shit! ", then it wont get caught?! A fundamental flaw I think. As most words are nouns they are VERY likely to be at the ...

Re: Help: How to reduce "out of memory errors" - IMAP users

Arg...can't edit again.

Avast seems to work day-to-day, but if a user was re-syncing everything, then Avast causes extreme load (quickly causes out of memory errors) on hmailserver and WILL not ever sync correctly -- just takes one user to cause havoc

Re: Help: How to reduce "out of memory errors" - IMAP users

The clients do all have offline storage, but I am assuming that only new/changed messages get downloaded to the client. Matt said that this would increase the overhead of the server immensely.

Still doesn't work on port 465 whether I use SSL/TLS or startTLS regardless of the settings on Outlook outgoing. Port 587 is working.

[000.293] We can use this server
[000.293] TLS is not an option on this server

Just wondering why port 465 is causing issue?

I can't test port 25 for SSL because it messes up the MAC users since apple mail auto detects settings, so it messes up their email connection if I get it wrong and its too stupid to repair the connection.

Yes I've read that, thanks. It seems to be a router port issue? And I still don't know exactly what gets encrypted and how to verify it is working on smtp which does work if I set the outgoing (in outlook) server to the server's LAN address.

Still getting the same issue after the update to 5.6 B2145. Any idea how I can troubleshoot this? Where is the character getting lopped off? The login info in the SMTP logs is masked so I cannot see the username that is used. However, in the banned list, the first character of the username is gone.
