How to send message to email with illegal syntax?

Post by dzord »

I have a problem with few customers, who has stupid email like "-lebedev-@mail.ru" - it's a real email of old customer. Long ago configured Zimbra without EFA can send to this email. But when I use EFA relay, I get error:
efa postfix/smtpd[4854]: warning: Illegal address syntax from unknown[172.17.1.10] in RCPT command: <-lebedev-@mail.ru>

What I need to do, that EFA ignore the bad syntax in the outgoing mail.
