Hi,

It seems I'm having an issue with James SMTP not announcing 8BITMIME. Seeing the following error in mail.log on certain emails:

dsn: . 550 MtaRejected \<someone(a)gmail.com\<mailto:someone(a)[gmail.com](http://gmail.com)\>\> -\> \<someone(a)mydomain.tld\<mailto:someone(a)mydomain.tld\>\>: on\_succ=0, on\_dly=1, on\_fail=1, never=0, warn\_sender=, DSN\_passed\_on=0, destiny=-3, mta\_resp: "550 5.6.3 id=02074-04 - Rejected by next-hop MTA on relaying, Conversion to 7BIT required but not supported"

This particular log entry seems to culprit:

Jan 5 08:39:40 smtp amavis[32190]: (32190-01) (!)requested BODY type is 8BITMIME, but MTA does not announce 8bit-MIMEtransport capability

Here's the log in its entirety. James is listening on port 10025:
