Have you considered changing over to pop3-ssl and imap-ssl? I fully |
| 13 |
switched over about six years ago and nearly every job I've had since |
| 14 |
has used SSL as well. I'd still recommend plain imap to be open on |
| 15 |
localhost for webmail to interact with it, but you should have far less |
| 16 |
problems. And less change of sniffers pulling user/pass from wireless |
| 17 |
connections in cafes. |
