Email Issues with K1000 appliance
We've had pop3 and smtp set up on each of our queues for at least a year now. All of a sudden after last wednesday it has stopped working and we just get a bunch of unexplained errors. We're using Office 365 Exchange Online, has anyone else experienced this issue recently?
Some of the errors:
kace2) [127.0.0.1] F=<FETCHMAIL-DAEMON@kace2> temporarily rejected RCPT <email@example.com>: Could not complete sender verify
SMTP error: 451 Temporary local problem - please try later
Aug 5 09:23:20 kace2 fetchmail: Query status=3 (AUTHFAIL)
Aug 5 09:23:21 kace2 fetchmail: Authorization failure on firstname.lastname@example.org@mdw-efz.ms-acdc.office.com
It appears that you have 2 issues based on the output you posted.
1) You do not have a DNS MX record for kace2.mccarthy.com
2) The credentials for the Pop3 mailbox that Fetchmail is trying to connect is incorrect.
