I have a pretty hairy problem. This morning I started noticing that I was not
getting certain emails - those that go through my gmail account. Then within a
few minutes I stopped getting any email.

I checked fetchmail and I noticed this problem for both my accounts:
it@...
it@...

both are showing Query status=3 (AUTHFAIL)

I contacted my email host and they said that isnt a address with them.

Feb 5 07:57:00 abcsmart fetchmail[5926]:
reading message abc@...@pop.where.secureserver.net:3 of 3 (1974
octets) (log message incomplete)

Feb 5 07:57:00 abcsmart fetchmail[5926]:
SMTP error: 501 5.1.7 Bad sender address syntax

Feb 5 11:07:38 abcsmart fetchmail[5915]:
Unknown login or authentication error on
abcsmart@...@gmail-pop.l.google.com


Now, I have gone through my fetchmail settings and there is nothing in there to
mess up my settings. But I dont know what has happened. Im not sure how to even
track down this issue either.

I did contact the fetchmail users group but since it is actually trying to get
mail, they think it is something else. I thought 'big help!'

Any ideas?
