[IMail Forum] Slow when client is sending

[Heimir Eidskrem]

Hello everybody,   One of my clients can download email quick with  no problems but when they are sending mail it is extremely slow.   4 minutes to send an email with an attachment of only 85K, they are connected using 128 ISDN.  When they try to send to another Imail server with a different company, the same file they have no problem and it only takes seconds.   They have several computers on the same connection with the same problem. I do not have anyone else reporting any problems.  I did look in my log files but can not see anything that indicates a problem.   Any suggestions?   Thanks,   Heimir
