Zitat von [EMAIL PROTECTED]:
Does anyone has this experience?
Spammers used the spam to ask horde/imp user to submit their account
info
(including password)
Somehow, user submitted.
And spammers use this user account to send a lot of bulk messages.
Yes, there have been numerous cases like yours.
Does anyone has this experience? I am just asking for suggest to
improve
in Horde/IMP webmail environment.
There is not much anyone can do but to keep their (and users) passwords
safe. Because Horde and IMP are open source, spammers do always have the
access to the source code and hence can always find a way to send spam
simulating a browser if they have correct credientials to use the
system.
Summa summarum: It's not the client programs fault if someone gets
credientials needed to send spam via the program. From a spammers point
of view the same thing can be accomplished with numerous other email
clients as well (programs running on workstations are off course a bit
harder to hack).
I do realize it is not the fault of the client programs.
The users should pay extreme attention to their credientials not to let
others get it.
But if in this case, you have any idea to avoid or just decrease its
impact to the mail server?
Let's say, control the maximun number of recipients in horde/imp TO field
and number of sending mails in a certain period of time by using horde/imp
in horde/imp configuration?
Both is possible since IMP 4.2.
