Citeren Bert de Jong <b...@elicom.nl>:

I hope you see the problem here.

Try to see this from the perspective of an inexperienced computer user.

If users are gullible enough to enter their login credentials based on a message like this, it won't make a difference if you display the 'real' e-mail address, they'll fall for it anyway (sadly).

The best you can do is to keep tabs on what usual and unusual traffic patterns are and act accordingly. Set limits on the amount of messages users can send per hour in your mailserver. Use the preferences system for IMP to limit the amount of messages and recipients per time period.

Bottom line: you're never going to be able to prevent abuse, but you can limit the impact it has.

Zitat von Bert de Jong <b...@elicom.nl<mailto:b...@elicom.nl>>:


Hi,


I'm curious if IMP's default is to not show the email address of the sender.


If you look at the attached screenshot

mirrored here https://i.imgur.com/ubRyIY6.png

you can see why one of our customers thought we were about to close

their email account, and why they would send back their password to

the "Email Administrator".


I did see the email address is shown when I move my mouse on the

text, but my customer was not aware of this feature.


Can I change a setting so that IMP will show the email address of

the sender next to the text?

(Next to "Email Administrator" in my case.)


No, such a setting doesn't exist.
