SOGo just an groupware extension for _any_ mailserver backend. So, the question is not the antivirus and antispam for SOGo. The question is antivirus and antispam for mailserver. Antispam has a place in SOGo too. I'd like to have an interface for the users to select how strict the spam-filter should be by integrating with sieve-spamtest/rfc5235. Maybe a block sender function, that pushes out a sieve script to the server to drop/move-to-Spam messages from a given sender. Also it would be nice if the SOGo webinterface had a Spam/not-spam button that would move messages to/from the Spam-folder. This could be used by http://wiki2.dovecot.org/Plugins/Antispam to train the filter. Block senders? How many senders need to block for correct spam filtering. One node of one zombie network sends about 100 thousand spam emails per day with randomly generated senders. Are you sure, you can stopped them with this feature? I don't think so. For correct filtering you need to use the followings in order of importance: 1. RBL checking with few reliable lists (ip and domain based too) - you can eliminate the 90% percent of spams 2. Greylisting - you can eliminate the 90% of remain spams 3. virus filtering, attachment checking - you can eliminate phishing, and trojean mails 4. content checking for spams (e.g. spamassassin) - you can eliminate the almost all of remain spams 5. use sieve filters for sa spam marked headers (if you want) Example. My mail host gets about 250-300 clean, real mails per day (total incoming mail traffic is about 2000 mails/day - yes, 80-90% of them are absolutely spam). The SA drops 5-10 mails into the quarantine per day (newsletters, advertisements, badly formatted mail contents - really spams, very rarely few false positive good mails). All of others are back off to senders. So, not perfect, cause usually one spam per week falls into my inbox. Yes, not with only sieve filters. The successful fight with spams there is at the gate, not at the mailbox. -- users@sogo.nu https://inverse.ca/sogo/lists

[SOGo] SOGo + fail2ban
I'm having a problem getting fail2ban working with SOGo. (2.0.7 on debian wheezy) There was a thread about this a while ago saying that 2.0.5 had fixed some logging of sogo for fail2ban to work -- I'm using 2.0.7. so I think this is a different issue. When I use the webmail interface to SOGo and type in the wrong username/password, the log file shows: Aug 21 22:40:04 sogod [13156]: SOGoRootPage Login from '127.0.0.1' for user 'asdf' might not have worked - password policy: 65535 grace: -1 expire: -1 bound: 0 The problem is the Login from 127.0.0.1 -- for fail2ban, it needs the ip on the user connecting, not the localhost ip. But since SOGo is access via the local web server and not directly via the client, I'm not sure how SOGo can get the ip address. Does this normally work for other people, or am I missing something in how fail2ban gets the information it needs. Or is there a trick to looking at the nginx/apache logs? I don't think this is relevant, but I have configured SOGo to go through an imapproxy running on localhost. Also, does SOGo log login failures over the calDAV / cardDAV interface, or just the direct webmail login? Thanks! Ben -- users@sogo.nu https://inverse.ca/sogo/lists

When you disabled the plugins and the memory usage was low, did you also disable Lightning? I doubt SOGo Connector/Integrator can leak that much memory, as they barely do anything when Thunderbird is running. -- Ludovic Marcotte lmarco...@inverse.ca :: +1.514.755.3630 :: http://inverse.ca Inverse inc. :: Leaders behind SOGo (http://sogo.nu) and PacketFence (http://packetfence.org) -- users@sogo.nu https://inverse.ca/sogo/lists
