Just thought i'd share this since i did research in the KB on this recently.
I did find a way in imail to up the smtp timeout.


(cut and pasted the kb article here since it was short)


IMail - SMTP Timeout does not conform to RFC 2821
Product: Version: Platform:
IMail 7+ NT,Win2000,XP

----------------------------------------------------------------------------
----

Question/Problem: Is there any way to change the SMTP timeout?

Answer/Solution: IMail's default timeout is 2 minutes (120 seconds). To
change this, run regedit. Go to:

HKLM\System\CurrentControlSet\Services\SMTPD32\Parameters

Create a new DWORD value named RECVTimeout and set the timeout in seconds.

The RFCs suggest a timeout of 300 seconds.

Stop and restart the SMTP service.

TTLs are usually applied to DNS records.

That's not TTL, that's "SMTP timeouts".  I don't think Imail exposes that
"knob" in the GUI, but you could step through the Imail registry to see if
such a timeout is in there as a default value.

But I don't think Imail SMTP timeout modification, if available in Imail,
is going to help.  AOL's MX are usually very efficient in sucking millions
of msgs.  Avg delay to send to AOL is under 5 seconds.  Today, they are a
bit slower:

Host/Domain Summary:

  sent cnt  bytes   defers   avg dly max dly host/domain
  -------- -------  -------  ------- ------- -----------
     375    18636k       0    19.4 s    2.6 m  aol.com

but you can see there is not one deferral. The above is for IMGate SMTP
settings  (lotsa knobs to play with in IMGate) :

smtp_connect_timeout = 120s
smtp_data_done_timeout = 60s
smtp_data_init_timeout = 60s
smtp_data_xfer_timeout = 60s
smtp_helo_timeout = 60s
smtp_mail_timeout = 60s
smtp_quit_timeout = 60s
smtp_rcpt_timeout = 60s

The above are fairly generous, since they are at least 3 times longer than
the average total delivery delay of today's slower AOL.

>I am running 7.13, and have looked in the FAQ's but have found nothing so

If you have Imail SMTP timeouts, these will be seen in your Imail logs as
deferrals of msgs when Imail tries AOL.
