Hello,

This is strictly not about Linux, but since Linux users have a whole lot of expertise in most other things, I thought I'd try asking here too.

I've been confused by a conversation I've had with an old I.T. veteran. I asked him why he did not enable IMAP on his company's email server (instead, allowing POP3/SMTP). His reply was that IMAP has security concerns (but he did not specify what), and that IMAP was susceptible to Directory Harvest Attacks.

I did some checking on the web, and found out that DHA is associated with SMTP. Nowhere did IMAP come into the picture. Since I am not an IMAP expert, I also did not want to challenge this IT pro who has at least a good ten years more experience than me.

So now I'm looking for a second opinion from anyone on this list who might be in the know.

I'd be grateful to anyone who can throw some light on the matter.

Thanks!
Kokhong
