I believe this is actually an MTA ( postfix) issue and not MailScanner. There is a lot of info out there in groups where this has been discussed.<div><br></div><div>On a similar note, I stick with all lower case addresses. While RFC compliant, not everything out there is compliant and could cause issues outside of your<span></span> enclave.</div>

<div>Hello,</div>
<div> </div>
<div>we have a Problem with our MailScanner / Postfix system.</div>
<div>When I send a mail to <a href="javascript:_e({}, 'cvml', 'T1485@domain.com');" target="_blank">T1485@domain.com</a> the address will be changed after processing to <a href="javascript:_e({}, 'cvml', 't1485@domain.com');" target="_blank">t1485@domain.com</a> .</div>
<div>Since the receiving system is requesting case sensitive addresses (and so defined in RFC) what have i to change for not rewriting the mail addresses?</div>
<div> </div>
<div>Thank you</div>
