Why me? This has little to do with wireless.
Well, what was changed last? You do keep server logs?
A "few links"? Could you be more specific? Anything inline that would block ports like a router perhaps?
Well, the first step to solving a problem is to blame someone. See if anyone in the office will volunteer. If not, assign the blame to the office masochist (every office has one).
Barf. OE and Ouchlook both trap the original error message, try to interpret it, and give you a bad guess as to what MS thinks it means. If the message came from an Microsoft mail server, you have a chance of figuring it out. If from some other server, it's a crap shoot.
Ok. That means the POP3 server replied with a message similar to "go away".
Digging with Google shows:
- Use telnet to get the original error message. Here's a sample POP3 session:
telnet mail.cruzio.com 110
+OK POP3 Ready mail.cruzio.com 0001b54a user jeffl +OK USER jeffl set, mate pass xxxxxxxxxxxxxxxx +OK jeffl has 10 visible messages (0 hidden) in 33288 octets. +OK 10 visible messages (33288 octets) stat +OK 10 33398 list 1 1752 2 1888 3 1753 4 1787 5 1755 6 2430 7 2270 8 2921 9 1459 10 15273 . quit +OK Pop server at bmail.cruzio.com signing off.
- I've had chronic problems with MTU discovery issues. Download fping 2.09 from formatting linkping your mail server with various size packets. For 1500Byte MTU, the max size is 1472.
C:\>fping 192.168.1.1 -f -s 1472 Pinging 192.168.1.1 with 1472 bytes of data every 1000 ms: Reply[1] from 192.168.1.1: bytes=1472 time=0 ms TTL=150 (trimmed...)
C:\>fping 192.168.1.1 -f -s 1473 Pinging 192.168.1.1 with 1473 bytes of data every 1000 ms: Packet size exceeds MTU and needs to be fragmented but DF set. (trimmed...)
Note that 1472 works, but 1473 generates an error. If you're getting much small MTU's, you may have a connectivity issue.
- Check if the mail server is running some kind of firewall (IPChains, IPFilters, etc) and see if it's blocking port 110 for some reason? Same with any intrusion detection system (IDS) or filtering software.
Meanwhile, you're on your own. My truck has an engine problem and it appears that I'm gonna be busy either doing a repair or finding a replacement.
