Problem: Clients using Outlook or Outlook express with SMTP
Authentication are occasionally not being authenticated properly. When
they attempt to send mail they will be prompted for user name and
password. Clicking OK (without changing the username or password)
anywhere from 4 to 10 times will normally send the mail.
Occasionally I need to stop and restart the SMTP service. The problem is
very erratic, it may work fine for 30 minutes and then fail every 2 to 5
minutes.
There have been no changes to the server sw or config or
IMail config and no major increase in users or traffic. Although the
problem seems to happen more often during heavy traffic periods.
IPSWITCH "Solution": I have spoken with Tanya at
IPSWITCH support extensively yesterday and today. She has been able to
recreate the problem by setting up a user on my server and attempting to send
mail using SMTP AUTH. Even so she has supplied no help except that it
MAY BE A LIMITATION OF IMAIL with the number of users that can authenticate at
one time and she has suggested to open my server up to relay mail for all
users. This is not a good solution since that would open me to spammers
and it would be near impossible to contact all of my users to have them turn
off SMTP AUTH. I also believe this could not be the problem since I only
have 60 domains with an average of 5 users each, which is well below what
IPSWITCH claims the product to handle and the traffic or users did not
increase at the time this started happening.
History: Currently running 6.03 with the latest
patches. Was running 5.08 when the problem started on Tuesday and
installed the upgrade that night with no improvement. This server has
been running IMAIL for over three years with no problems. %.08 has been
installed since around December.
Running 60 domains, with unique i/p's with approximately 350
total users.
