I am having issues receiving emails from the Internet larger than 15-20MB even though I have a 50MB limit set on Exchange 2010. So far I have configured the following with a 50MB limit:
Get-TransportConfig | ft name, MaxSendSize, MaxReceiveSize
Get-ReceiveConnector | ft name, MaxMessageSize
Get-SendConnector | ft name, MaxMessageSize
but when I try to send an email with only 20MB in size I will receive the following NDR error:
#554 5.2.0 STOREDRV.Deliver.Exception:MessageSubmissionExceededException.MapiExceptionMaxSubmissionExceeded; Failed to process message due to a permanent exception with message Cannot complete delivery-time processing. 16.55847:92260000, 17.43559:00000000A6020000000000000B00000000000000, 255.23226:00000000, 255.27962:0A000000, 255.27962:0E000000, 255.27962:0A000000, 255.27962:9E000000, 255.17082:DA040000, 0.18273:00000000, 4.21921:DA040000, 255.27962:FA000000, 255.1494:43000000, 255.1238:13800000, 6.8660:0F010480020151000B000658, 0.18658:0F010480, 6.11956:0F010480020151000F010480, 6.15604:0F010480020151000B001F0E, 6.21970:0F010480B084EC810F010480, 6.21970:0F010480B08485810F010480, 6.21970:0F010480B0841F81B0846680, 6.21970:0F010480020113100F010480, 1.64319:003C0000, 1.39743:78520000, 4.45016:DA040000, 0.57304:0F010480, 4.5041:DA040000, 4.4465:DA040000, 4.6833:DA040000, 0.50217:40001900, 4.5093:DA040000, 4.5318:DA040000, 4.10104:DA040000, 0.57449:0F010480, 4.6025:05000780, 4.5257:05000780, 4.4606:DA040000, 255.1750:00000000, 0.26849:00000000, 255.21817:DA040000 ##
Why would it be failing even though there is a 50MB limit set on everything? This error almost seems more like a timeout rather than a message size limit issue. Is there a receive timeout setting in Exchange 2010 that should also be changed? I am at a loss with this right now.
Any help is appreciated.
