I'm hoping someone here may have encountered this problem and can suggest a solution. I'm running postfix 2.5.14 on Snow Leopard for use as a personal mail server. My server is configured for SMTP relaying (using the MailServe gui) and to use the Mac user accounts (plaintext passwords) for authentication. Every 10 minutes, give or take a few seconds, the same eight lines appear in my mail log (with fresh process numbers for the smtp demon):
postfix/smtpd[18872]: disconnect from sanacacio.net[65.19.28.60] postfix/smtpd[18872]: warning: sanacacio.net[65.19.28.60]: SASL PLAIN authentication failed postfix/smtpd[18872]: error: CF: Credentials could not be verified username or password is invalid. postfix/smtpd[18872]: connect from sanacacio.net[65.19.28.60] postfix/smtpd[18865]: disconnect from sanacacio.net[65.19.28.60] sanacacio postfix/smtpd[18865]: warning: sanacacio.net[65.19.28.60]: SASL PLAIN authentication failed sanacacio postfix/smtpd[18865]: error: CF: Credentials could not be verified username or password is invalid. sanacacio postfix/smtpd[18865]: connect from sanacacio.net[65.19.28.60] My domain is sanacacio.net. In addition, whenever I send an email I get an error like this: sanacacio postfix/local[19315]: od[getpwnam_ext]: no attribute dsAttrTypeStandard:MailAttribute in record for user . . . Can anyone suggest how I can fix this? As a workaround I've set up the server so it doesn't require SSL for smtp relay. But I want to be sure it is secure as possible. Thanks in advance.
