We lost our network connection recently for about an hour and I was going to explain to someone how mail servers work when it came apparent that I did not know the exact retry rate that other MTA servers use.
So, I have been looking for information on mail server (MTA) retries. There does not seem to be any standard except 5 days seems to be the max. Am I right here ? Does anyone know if there is an RFC for mail servers regarding mail retries ? I found this but it does not explain the details: http://www.faqs.org/rfcs/rfc1894.html What is the typical retry rate for most mail servers out there ? I.E. MS Exchange, Sendmail, Etc. I use the Postfix MTA, mine seems to say 'try to resend every 1000 seconds for 5 days': postconf | grep -i queue maximal_queue_lifetime = 5d queue_run_delay = 1000s Here is a [Random] Exim Config which specifies the MTA a retry rate diffently: # begin retry # Domain Error Retries * * F,2h,15m; G,16h,2h,1.5; F,4d,8h # This single retry rule applies to all domains and all errors. It # specifies retries every 15 minutes for 2 hours, then increasing retry # intervals starting at 2 hours and increasing each time by a factor of 1.5, up to # 16 hours, then retries every 8 hours until 4 days have passed since # the first -- ------------------------------------------ Ted Knab Chester, MD 21619 00010010100001101100011011010110101001100100111011001110 00000100100001100100111010100110000001000101011010101110 11001110001011100000010010000110000001001011011010010110 11100110010011101000011000101110111101100100111010011110 00000100001101101001011001100110101001100110011011110110 01001110101101100000010011101110100101100010111000010110 00000100100001100000010000101110010011101111011000001110 10010110110011101011011000000100011001101111011001001110 00000100110001101111011010110110000011101010111000101110 1010011001001110110011100111010001010000 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
