Head's up:
A few days ago, I noticed some lamer trying to dictionary attack the Glade's POP3 service. Not to worry -- it didn't succeed. Also, this is a pretty common occurrence these days. I see it at work a lot, too. Nevertheless:
- If you have a gladerebooted email account, please be sure to use a strong password. I recommend using Keepass for this kind of thing. By default, it will handily generate 100-bit (ish) passwords for you.
- I've added an iptables filter to thwart this kind of thing. Basically, it tracks the number of connections each source IP tries to make to IMAP(S) and POP3(S). If an IP exceeds certain thresholds for connections/second, it gets banned from all communication with the server for one hour. Any attempt to connect to the server before the ban expires extends it for another hour.
The thresholds are:
- More than 5 connections in 1 minute
- More than 15 connections in 10 minutes
This only matters if you're using IMAP/POP3 directly. Web mail (squirrelmail) use is a separate thing. The filter doesn't know (and can't tell) if your connections successfully authenticate or not, so if you exceed these limits, you'll get banned even though you are a legit user. I doubt this will affect anyone, but even so:
TL;DR: If you use a glade email account with Thunderbird, Outlook, etc. do not try to fetch mail more frequently than about once a minute or you may get temporarily blocked from the Glade (all of it).
If this somehow happens to you, let me know via email (obviously you won't be able to PM me
