Hi, I'm a bit frustrated with this issue. I got a linux server with a postfix error. I can send emails to all the addresses, but I can not receive emails from some people/servers with the next error: <-- 220 xxxxxxxxxxxx ESMTP Postfix --> EHLO xxxxxxxx <-- 250-xxxx-xxxxxxxxx <-- 250-PIPELINING <-- 250-SIZE 10240000 <-- 250-VRFY <-- 250-ETRN <-- 250-STARTTLS <-- 250-ENHANCEDSTATUSCODES <-- 250-8BITMIME <-- 250 DSN --> MAIL From:<xxxxxxxxxxxxxxxxxx> SIZE=23929 <-- 530 5.7.0 Must issue a STARTTLS command first --> QUIT For gmail, hotmail and other public servers all its ok. Some one can help me? Regards
