Description of problem:
Sending mail via an IMAP account, regardless of message length, type,
attachments or not, takes almost 1 minute, sometimes longer. This was
not the case under RH9 and 8. While waiting, the message and the send
message progress window both continue to appear on the screen, but the
progress window shows no progress.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Open Mozilla mail (IMAP account)
2. Write and then Send message
Actual Results: The time between pressing the [Send] button and the
message actually being sent is at least one minute, regardless of the
type or length of message. The progress window does not show progress,
though it does disappear once the mail is sent.
Expected Results: The mail should be sent off, and the message and
progress bar should disappear, in a rather short time (a couple of
seconds or so). Also, the progress bar should show progress.
There are two components to this: 1. Sending the mail and 2. making a
copy in your Sent folder.
If you look at the messages, it should tell you which part is hanging.
I'm guessing that you're having a DNS problem. When I use localhost
as my MTA sometimes sendmail takes a long time looking up the hostname
of the mail that is being sent, and it looks like it takes a long
time. Restarting sendmail usually helps. This happens in a lot of
cases because sendmail is started before the network is up, and DNS
information isn't current.
The information we've requested above is required in order
to review this problem report further and diagnose/fix the
issue if it is still present. Since there haven't been any
updates to the report in quite a long time now after we've
requested additional information, we're assuming the problem
is either no longer present in our current OS release, or
that there is no longer any interest in tracking the problem.
Setting status to "CURRENTRELEASE", however if you still
experience this problem after updating to our latest Fedora
Core release and are still interested in Red Hat tracking
the issue, and assisting in troubleshooting the problem,
please feel free to provide the information requested above,
and reopen the report.
Thanks in advance.
