Thanks for the tip. I have added this to .mc:
dnl alternate relay port
MAILER_DEFINITIONS
relay_port_587, P=[IPC], F=mDFMuXa, S=EnvFromSMTP/HdrFromSMTP,
R=EnvToSMTP, E=\r
\n, L=990,
T=DNS/RFC822/SMTP,
A=TCP $h 587
Created a mailer table:
example.com relay_port_587:example.com
And when I send to this domain, I get this in the maillog:
NOQUEUE: SYSERR(root): /etc/mail/sendmail.cf: line 1718: unknown
configuration line "relay_port_587, P=[IPC], F=mDFMuXa,
S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP, E=\\r"
Aug 19 11:56:50 rncserver sm-mta[70987]: NOQUEUE: SYSERR(root):
/etc/mail/sendmail.cf: line 1721: unknown configuration line "\\n,
L=990,\n T=DNS/RFC822/SMTP,\n A=TCP
\001h 587"
Guess I have messed something up here, see anything obvious?
