Is there anything else on the ISP server that you can trial a connection to? Say FTP? or or even a plain text server such as HTTP? If there is, then try connecting to that service and see if there is a similar lag. That will eliminate a general network lag problem and point solely to the IMP server. Are you aware of any other users having the same problem (Most ISPs have a "community blog" page somewhere where customers post queries/comments/complaints.)
- I don't know. I'm not certain where I'd look to see if there was a
FTP/HTTP server to be honest.
Well, the quickest way to check without trying a network scan (which the ISP might consider hostile....) is firstly to check the IP address of the IMAP server (dig, or nslookup whichever is your preference) then try a speculative connect to that address with an FTP client (or netcat or telnet to port 21) and a similar test to port 80. You could also try a connection to port 23 though I'd be astonished if an ISP left that open. Maybe try port 22 if you think they run ssh on the standard port.
Whatever you try, it might be a good idea to tell the ISP that you intend doing that. The UK CMCA can criminalise such action and you might set off all sorts of alarms. But the fact that you want to test this might make them wake up to your problem.
- I've asked on the forum page but no-one else seems to be having
this problem. (It isn't super busy most of the time though, so ...)
And no-one from the ISP has responded?
