The mailing list for listmasters using Sympa

[Chris Peck <address@concealed>]

I’m getting ready to upgrade to 6.1.22 and going through the sympa.conf 
parameters to set them to ‘reasonable’ values.  One that I’ve come across, 
that I have to set is the list_check_smtp and list_check_suffixes.  All of 
our email to the Sympa server goes through a gateway system that cleanses it 
and them passes it on. It also allows sending email to address@concealed 
(although the Sympa Server exists at lists.domain.com).  This requires me to 
check requests for new lists against the SMTP server for that domain 
(although, I could look in LDAP to find the same information).  Setting this 
works fine, except, our SMTP servers have a delay on response set (which I 
can’t seem to tweak for the Sympa server).  This effects the response for 
creating lists - it slows it down. considerably.

The question is, is there another way to test the existence of a list email 
address, either via LDAP, or, even modify the behavior for list_check_smtp so 
that it simply checks if the existence of the email address of just the list 
exists without specifying list_check_suffixes (have the default set to none, 
just look for address@concealed)?

Thanks,
chris
