Here's what might seem like a minor issue, but we have a customer who is rather upset. It seems he wants to create a signature using webmail, but can't believe he's getting an error message limiting him to 64kb. (I have no idea why he needs such a large .sig - all of mine are 1-2k, max.)

After way more time researching this than is considered cost effective, we can't seem to find what the size limits are for any of the webmail portals, nor whether they can be changed.

Any info on signature size limits?

Hello,

Could you provide an example of a signature that's exceeding the size limit so we can reproduce the issue? Also, can you verify the specific steps used to reproduce the issue?

Thank you.

The customer still hasn't responded with any further info, but we'd still like to know what, if any, .sig size limits there are in the webmail portals.

Hello,

There shouldn't be a limit on the signature size itself, but it's possible the user is exceeding another limit. It seems more like a limit that would come from a PHP variable. We'd need to know the specific webmail application that was used, or the specific error message that was encountered.

Thank you.

That's what we figured, but with no specifics from the customer, we're not going to worry about it.
