pdf-corrupted

[Mohammed Ejaz]

Hello, All,  

We  have some problem  with one of the sender whose using Exchange 2010 with
TLS option Enabled,  whenever he is sending an email with pdf attachments it
keeps get corrupted. up on checking postfix logs it says delivered without
any problem. but our Mail application (Communigate)  complain as follows.

 

08:55:16.0 5 SMTPI-114694([64.207.65.117]) s-out: 354 Enter mail, end with
"." on a line by itself\r\n

08:55:26.4 3 SMTPI-114694([64.207.65.117]) failed to receive message body
(764206 bytes). Error Code=TLS block signature is incorrect

The same sender sending same email with a pdf attachment   to yahoo, Hotmail
and Gmail etcc.  it went through well without any problem. 

Therefore, anyone can give us any clue what would be the problem 

 

Our setup is 

 Front End (we use to filter/scanning  the email)

 Mailscanner,clamav,spamassin with postfix mail servers 

 Backend.

 Communicate (mail application)  where the actual mailboxes are existed.

 Note: if we eliminate the mail scanner and postfix (front end mail server),
then everything goes well. 

common thing between the sender and recipient is postfix and mail scanner. I
have checked with mail scanner. but didn't get much help.

 

 

Regards,

message copy after successfully got delivered,

actual mail box exists  in it.
